Helium-3: edit of 2023-04-21 15:31
The comment that accompanied this edit:

Helium 4 is not an isotope, it is elemental helium. An isotope has a mismatch number of proton to neutrons. He 4 has 2 of each.

is nonsense. See the article on isotopes of helium. I started to undo the edit; however, I am not sure that previous version of the article reads better with the parenthetical comment which was deleted:

(in contrast, the most common isotope, helium-4 has two protons and two neutrons)

Caveat: I have a PhD in applied physics and my idea of whether or not the article reads better with the above may not be correct for general readers. Therefore I'll leave it alone, but welcome discussion. JoshuaWKnight (talk) 21:48, 11 May 2023 (UTC)
