Yeah, the only reason I replied was because you were responding to the calcium dude above, then said “s-block”. Just wanted to spread the good word of the 9th-most abundant element in the universe 🙏

Magnesium is fine (see response above). https://invidious.darkness.services/watch?v=Q_4I30Nz_b0 Just don’t vomit on it before you lick it, 'cause it’ll get spicy with acid.

I have elemental magnesium (4 ~50g ingots, I keep it in my library in a barely-sealed ziplock). it’s shelf stable and doesn’t react violently with water. Want me to try licking it and let you know? (hint: at worst it’ll make a minuscule amount of milk of magnesia)

ETA: Would I stick my tongue in pyrophoric magnesium powder? No, and you wouldn’t do that with pyrophoric aluminum or zinc powders, either, but that doesn’t stop me from using (or licking) alumnum foil. Proof: https://invidious.darkness.services/watch?v=Q_4I30Nz_b0
