Chemist here: all the reds are correct but it would take so much time to explain why so many of the greens are super concerning. Every time I see this reposted it’s so concerning…I should just spend the 17 minutes and save a copy pasta response of everything horribly wrong with this.
Edit: page 1 on the SDS for pure sulfur.
I’m pretty sure that licking pure magnesium would make your tongue explode too.
Definitely not licking pure lithium, sodium, or any of the alkali (s-block) metals. My tongue is wet. That shit explodes in water, yo.
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
The LD 50 for sulfur is 2000 MG per kilogram body weight. So you’d probably be fine licking it. You can’t just go off the msds.
My degree is in bio but if I’m remembering my coursework correctly, this is the legend that’s supposed to be on it.
From my elementary knowledge of chemistry:
I had to go looking for Mercury and Lead and sure enough they look about right.
Column 1 reacts with water so you bet that’ll hurt. Hydrogen needs a boost to start reacting with oxygen so no naked flame is recommended.
Anything in column 7 are desperate to rip electrons away from molecules so yes, permanent damage to your tongue and mouth.
Uranium is alright if you lick it once. A guy ate uranium cake once on TV.
The ‘Please reconsider’ lot seem to be a good way to die a horrible death by radiation.
Tc I believe is technetium which is radioactive and emits gamma rays, perhaps not soluable so stays in your body and you become gamma-man.
Needs a “how fast can you move your tongue?” label for the unstable elements.
Is it really that bad to lick something that disappears after nanoseconds?
Elemental mercury isn’t very bioavailable so licking the surface of a pool of mercury isn’t going to hurt you much if at all. (Assuming you just do it once). Plus the density of mercury is going make it hard for you to slurp up a significant quantity the stuff anyway.
If you want to know about the horrible potential for mercury to mess you up look for stories about dimethyl mercury exposure. Its the fat soluble varieties that give mercury it’s reputation.
The story of the professor who was studying dimethyl mercury is terrifying
Chubbyemus take on it was pretty good
