OK, who's copying who? I just found almost the exact same entry as this one (word for word) here http://experts.about.com/e/b/bo/Boron_group.htm . It doesn't *seem* to come from here like Answers.com does. Anyone know? --Stretch 06:39, 5 September 2006 (UTC)

Change in Class
I changed the class because it seems big and good enough to be a start class article. If anyone has any objections, feel free to post under here. --Geo7777 (talk) 14:28, 16 May 2011 (UTC)
- Objection, there are too many web-based sources, and most of these aren't that reliable (wiki.answers.com). There's very little actually useful content for now. I'll change it back first (but don't worry, because I'm thinking of getting this to at least C-class first). Lanthanum-138 (talk) 14:28, 19 May 2011 (UTC)
How about now? i added 9 non web-based sources and i added an 'isotopes' section and i just finished working on the 'history' section. plus, I included a table. please reply. --Geo7777 (talk) 09:08, 29 May 2011 (UTC)
- Goody. I'm promoting it. Thanks! Lanthanum-138 (talk) 14:34, 4 June 2011 (UTC)
- Yeah, it's getting nice! About the table: there's also InH[1], add it please :) and also, why not use this format:
Element | Oxide | Hydride | Maybe more, what about fluorides, chlorides or sulfides? |
---|---|---|---|
Boron | its oxide | all hydrides | |
Aluminium, so on |

BTW, I'm not sure referencing level depend on Start-classness (think of a better expression?) If really so, take a look on lawrencium, because it may be therefore still a Stub--R8R Gtrs (talk) 15:00, 4 June 2011 (UTC)
- And also, I'd like to have refs on neutral elements(IV) hydrides, as well as TlO2 (a superoxide?) and all element 113 compounds--R8R Gtrs (talk) 15:04, 4 June 2011 (UTC)
- The Uut compounds I think are webelements.com speculation. While they certainly are plausible, there don't seem to be solid references for them. Lanthanum-138 (talk) 02:39, 5 June 2011 (UTC)
Ok, I am beginning to work on the article and make the changes you suggested. But you might need to go over the spelling and grammar, I'm not very good at that. --Geo7777 (talk) 08:47, 5 June 2011 (UTC)
Done I managed to do that, but I wish that I could find more references and especially for the table. I'll look for them later. --Geo7777 (talk) 13:38, 9 June 2011 (UTC)
R8R Gtrs comments
Too little too late, still some comments to make the article better:
- Electronic table isn't put in the lead right. Move it down the article.
Done
- "The group has previously also been referred to as the earth metals and the triels, from the Latin tri, three, stemming from the naming convention of this group as Group IIIB." Not reflected in History section.
Done
- "Boron is considered a metalloid, and the rest are considered metals of the poor metals groups." first of all, "metals of the poor metals groups" sounds weird. What about just "poor metals"? Also, what about ununtrium? It is still not confirmed to be one.
Done
- "Boron occurs sparsely probably because of disruption of its nucleus by bombardment with subatomic particles produced from natural radioactivity. Aluminium occurs widely on earth and in fact, it is the third most abundant element in the Earth's crust (7.4%)." OK, but why no mention of heavier ones? At least that they occur in much lower quantities.
Done
- I don't like indium picture, it gives little expression of how metals looks. Anything to replace?
Done
- I found another picture of indium rope in the main article, do you think it is better?
- "The boron group is notable in its trends and by some of its elements' characteristics. For example, all of the elements in group 13 are silvery-greyish metals or metalloids." Give another example, boron seems to look completely different from the metals. Maybe instead that boron differs from other elements (borides formation, hardness, refractoriness, volatility of BF3 but not AlF3, absence of metallic bonding, so on)?
Done
- "This is due to a trend that shows that the stability decreases and rarity of compounds increases with hydrogen." No, the trend is due to this, unless some theoretical proof is given.
- I didn't understand what you mean by this. Do you mean that i should reference it?
Done, I decided to take it out completely.
- I didn't understand what you mean by this. Do you mean that i should reference it?
- "indium oxide (In2O3)" it's indium(III) oxide and it's amphoteric as well. "thallium oxide (Tl2O3)" is thallium(III) oxide. What about In2O and Tl2O?
Done
- "Fluorine, the first halide" fluorine is a halogen that forms halides :)
Done
- "It is even hypothesized that ununtrium could form a compound with fluorine, UutF3, before spontaniously decaying due to ununtrium's radioactivity." Proof?
Done, hope that I got it right.
- "and also hypothetically reacting with element 113." proof?
Done, same as above because i couldn't find a "solid" reference.
- "Bromine will react too with most elements, although it is less reactive than both chlorine and fluorine." Seems like you're describing bromine, and not group 13 compounds.
Done
- "Astatine, the heaviest halogen, has only formed a few compounds due to its radioactvity and short half-life so it is extrapolated to have compounds with the metals including the boron group." proof?
Done, same as the other two
- "Gallium, like aluminium, is a good conductor of heat,[13] almost exactly like indium. Thallium, the heaviest non-synthetic element in the group, is also a good conductor of heat" reword
Done
- Can you check to see if i reworded it correctly? :)
- Try something like "Boron, being a metalloid, is an insulator at room temperature, but a good conductor at high temperatures. Unlike boron, the metals in the group are good conductors at usual conditions." Just if info on the metals is the same, no need in separate sentences.
- Can you check to see if i reworded it correctly? :)
- "The shortest stable isotope, however, is extremely short, being boron's isotope with the least neutrons and a half-life long enough to measure. it is 7B and its half-life is a mere 350±50 x 10−24 s." Is this really needed?
- I put it in purely for comparasion, because I felt that if we put the isotope with the longest half-life that we should put the shortest one too, but if you feel that it is not needed I can remove it.
- "This group is special with its isotopes because it contains some of the heaviest stable isotopes ever found. Only lead has a heavier stable isotope." Maybe add that all isotopes with Z>40 are theoretically instable? See stable isotope for details. Also, 115In is not stable. In fact, maybe more contents here? (Maybe not)
Done
- I will try to add content after.
I'll add more later--R8R Gtrs (talk) 10:33, 22 June 2011 (UTC)
I did the easy and quick ones now, I will work on the harder ones (such as finding references) that take longer time later. I appreciate your comments and the time you took to take a look at the article even though you are very busy. By the way, I'm sorry about the fluorine FAC results. But it is still a really good article, and it is a status that this article probably will never get to. Thanks again --Geo7777 (talk) 15:22, 22 June 2011 (UTC)
- "Ununtrium is a synthetic element and thus it is not found in nature." It's vice versa — it's not found in nature but is known to be synthesized, thus "synthetic". Think about it.
Done, though mabye not in the right place.
- "The real metalloid was not known in its pure form until a thousand years later" confusing. I can't think of constructive criticism, but think more, please.
Done
- "boric oxide" it's on yours, but why not boron oxide?
Done
- "Aluminium, like boron, was first known in minerals before it was finally extracted from it." Isn't it true of half the periodic table?
Done
- "Indium is the fourth element of the boron group and yet was discovered before the third, gallium, and after the fifth, thallium." why not putting them in chronological order? Periodic one is known anyway already by those who read it word by word.
Done
- Bring spellings (and the whole language) to the same standard. "oxidise" is a British thing, while "synthesize" is American. Also, punctuation, some words and spellings differ. Choose yours. See Differences between American and British English for details.
Done, I skimmed it for other spelling differences and found a few.
- I think Dubna team should be mentioned first (ununtrium). The thing happened in Dubna anyway.
Done
- "in America" in United States? And "in" should be replaced with "of the", since it happened in Russia. Maybe reword at all?
Done
- "Boron is one of the lightest elements with an atomic number of only 5, yet it is almost never found as an free element in nature." Lithium is even lighter, and even more reactive. Helium is even lighter, but not reactive at all. Think of better wording.
Done
- Article has too many "in fact,"s. Not only here.
- "Indium, like gallium, is a rare element in the boron group." It's clear already. Just say it's rare, and don't mention gallium.
Done
- Back to Isotopes: gallium has two stable isotopes; indium-115 may be worth mentioning
- It's Earth, not earth :)
Done
- "sis-able" huh?
Done, put as sizeable.
- "Ununtrium is a synthetic element with no stable isotopes. Therefore, it is never found in nature." Already mentioned in the article, remove?
Done, changed it instead of deleting it.
- There's a guideline that tells to use approximate number in brackets when the first one is approximate. "(about 5500°F or 3037.77°C)" to "(about 5500°F or 3050°C)" Add
Done
- Toxicity section is a way too long para, break it.
Done
I looked through last three sections not very carefully. I won't strike your things, you can deal with it, as I see :) I'll maybe add more. Look for more yourself, and try a peer review once you're done with yourself and my things--R8R Gtrs (talk) 14:15, 23 June 2011 (UTC)
Comments by stone
The chemistry of the group should be described in a way that what are the common properties, like oxidation state 3+. The increasing stability of oxidation state 1+ and making it the dominant one in thallium. This comparison of the whole group should be done in every section. --Stone (talk) 19:54, 23 June 2011 (UTC)
I'm not very sure about what you mean, do you mean that instead of putting it like it is now, we should put it as such: ===oxidation state 1+=== and so on? If you mean that, it will take a long time and almost complete rewriting of it, but I am thinking to put it as a seperate subsection before "halides" and "hydrides" and "oxides", so I hope you think it is okay. Thanks though for taking the time to do see it. :) --Geo7777 (talk) 16:05, 27 June 2011 (UTC)
Reply to Comments
Hi, sorry I won't be able to go on wikipedia that much I'm going to be away much of the time. I will try to fix more of the mistakes but you should probably know that I'm terrible at spelling and also I'm still in school (not graduated) so I may not have enough time for everything but I really find this interesting so I will try as much as possible. Thanks for the comments, they really helped to shape up the article. I will think about doing a peer review but i thought that it was for very developed articles like A-class but i still would be delighted to try it. Thanks :)--Geo7777 (talk) 18:58, 26 June 2011 (UTC)
