Isotopes

Deuterium and tritium are also gases. --Leiem (talk) 02:31, 15 December 2018 (UTC)[reply]

You are going to have to say more to get a meaningful improvement or response. Some gases have multiple names. Graeme Bartlett (talk) 07:57, 6 March 2023 (UTC)[reply]

Missing entry

Can we add the compound NO₂ (Nitrogen dioxide) into the main list? With a boiling point of 21°C at 1atm, it is obviously a gas at STP. It is a well known chemical compound. Note that currently in this list, the least dense (i.e, has the lowest molecular weight) gaseous compound which is not colorless (beside diazomethane) at STP is ozone (M≈48 amu). After the addition of an entry for NO₂ (a red-orange gas at STP, M≈46 amu), this situation will change. 2402:800:63AC:E276:E4F9:9F37:A614:73CD (talk) 12:04, 1 April 2023 (UTC)[reply]

This appears as "Nitrogen tetroxide" boiling at 21.15. Apparently NO₂ is unstable and dimerises to this at the cooler temperature. I suspect if it did not dimerise, the boiling temperature would be lower.Graeme Bartlett (talk) 12:34, 1 April 2023 (UTC)[reply]

And I think you missed flourine as coloured. Graeme Bartlett (talk) 21:57, 1 April 2023 (UTC)[reply]

116-15-4 duplication

Hexaflouropropene is listed also as perfluoroporpene. Boiling point needs to be checked. Graeme Bartlett (talk) 12:23, 14 April 2023 (UTC)[reply]

Common Gases and its full form and its formula

Common Gases and its full form and its formula 223.123.112.73 (talk) 17:44, 21 June 2023 (UTC)[reply]

What do you mean by that? I tried to give a formula that could indicate the structure, rather than just the number of atoms. Most of these gases are not "common". Graeme Bartlett (talk) 08:21, 22 June 2023 (UTC)[reply]

You can count the entries. I did not put the number in the intro as I keep adding entries. You may dispute the definition of a "gas" for this page so entries may need to be added or excluded. A few are isotopologues, so you may not want to include them. Also the list is incomplete, so the number will be too small. One simple way to count is to copy and paste the table into Excel spreadsheet and see the number of the last row. Graeme Bartlett (talk) 02:55, 24 April 2024 (UTC)[reply]
