Column
There is a column on the right entitled "Range of natural variation" with no items in it. This is idiotic. — Preceding unsigned comment added by 92.26.7.176 (talk) 13:06, 18 February 2013 (UTC)
- In the article Isotopes of copper, some numbers do appear in the column on the right, for the two stable isotopes of copper. — Preceding unsigned comment added by 92.27.109.117 (talk) 11:32, 19 February 2013 (UTC)

The only beta-stable nuclide of odd mass number with N/Z = 1.5
195Pt is the only beta-stable nuclide with odd mass number such that N:Z = 3:2. 5n2nX is beta-stable for n = 1, 26, even numbers from 30 to 46 and 39 (not primordial for n = 1 or even numbers from 42 to 46). Cristiano Toàn (talk) 08:32, 28 February 2024 (UTC)For even n from 36 to 40 these nuclides are also double bete-stable
Bound-state β− decay of 195Pt: reference required?
Could anyone please give some reference of the bound-state β− decay of 195Pt to 195Au, of which, unlike in the cases of 163Dy and 205Tl, I can't find any? 129.104.241.214 (talk) 23:59, 9 October 2023 (UTC)

Half-life of 190Pt in dispute
[1] proposes a half-life of 4.97(16)×1011 years, 4.49(5)×1011 years in [2], 3.9(3)×1011 years in [3] and 3.7(3)×1011 years years in [4]. Note that a precise determination of half-life of 190Pt is essential in radioisotopic age determination of some ores and meteorites. 129.104.241.214 (talk) 13:01, 23 December 2023 (UTC)
- NUBASE2020 lists a half-life of 483(3) Gy, so we will go with that one. –LaundryPizza03 (dc̄) 13:16, 23 December 2023 (UTC)
