Talk[edit]


can ayone give an example of when these unstable isotopes exist? For instance, what circumstances create Au 191 which exists only for 3 hours? And is Au 191 solid and look just like gold 197 for those three hours, or does it only exist in solutions? Just something I'd like to know.

OE79Au199[edit]

The instability of OE79Au199 (Z79Gold) represents a break in an isotope stability line with formula (A=3Z -38) that runs from 64Thullium (EE64Tm154) through 78Platinum EE78Pt196 and is instead monostable at OE79Au197 with only 39 extra neutrons and a stability trend formula of A =3Z -40. This is a break in the A =3Z - 38 trend line which would have otherwise continued through 82Lead at EE82Pb208. And then on occasionally up to 94Pu Plutonium at EE94Pt244.

Missing stuff[edit]

What about 205mAu, 206Au, 207Au, 208Au, 209Au, and 210Au? They all have been synthesized, have they? Despite this, the gold nuclides are like the transactinides: they all have been synthesized, but due to their short half-lives, they don't actually exist. --3.14159265358pi (talk) 18:00, 3 December 2011 (UTC)

Could someone that knows that the gold nuclides listed in this section exist post the nuclides' information on the table, in the form of six additional rows at the bottom of the list? --3.14159265358pi (talk) 18:03, 3 December 2011 (UTC)

Iridium not "heavier" ?[edit]

I thought Iridium (Ir, element number 77) was the element with highest density. And the 193-isotope is stabile, isn't it ? Stabile Iridium density 22.56 g/cm3. While density of stabile Gold just is 19.32 g/cm3. (Both at +20C). Am I wrong ? Boeing720 (talk) 19:45, 5 July 2012 (UTC)

Use of Au in nuclear weapons.[edit]

Just wanted to add that the W71 ABM warhead used a gold secondary tamper for its high x-ray emmisitivity, as x-rays were the kill mechanism for this weapon. Clarification in the W71 article.
