    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.

    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.

    What’s wrong with licking osmium? I know if heated in oxygen it will form osmium tetraoxide which is toxic, but a solid chunk of elemental osmium I thought was inert and I could keep it in my mouth all day if I wanted ( I do).

      Can you, though? Can you lick a gas? Am I licking the atmosphere when I stick my tongue out?

      Plenty of them are also so rare that there isn’t enough of them to form any lickable matter; solid, liquid or gaseous.

      Some have such an incredibly short half-life, you cannot lick it before it decays into something else.

        This really feels like we’re going to descend into an “is water wet”-style debate. Those are always fun.

        I think I’d still consider it a lick even if you just contact one atom of a substance to your tongue. You could even fire it at your tongue with the LHC and I’d still be willing to go along with calling that a lick, using the term very loosely.

        I’m less sure on the gas, but fuck it, sure, sticking your tongue into a gas can be a lick between friends. Alternately you could condense/freeze it and lick that form, but that might be worse.

        There’s no getting away from the idea that it would be very difficult to lick an atom with sub-millisecond half life. Unless… you create it already inside your tongue! I’m sure we could do that somehow. Probably involving magnets.

    Mid at best. There’s a lot of stuff you don’t want anywhere near your mouth on there.

    lol You don’t need a table to tell you whether or not you should like an element. Like ‘em all! Also, whoever made the pic misspelled “like” as “lick”. jsyk.

      Nah, metallic lead is pretty solid. Licking it doesn’t really do much. You shouldn’t ingest lead, but you don’t really ingest it by licking a piece of metal.

          Well, when you lick mercury, you’re actually going to swallow a lot of it. Thankfully, you’ll poop most of it out, and as long as you do it once, it won’t kill you.

          But if I had to pick between licking lead or mercury, I’d go with lead.

            Oh yeah. I am om team lead. The problem with Mercury is the vapor that ridiculously easy methylates when heated, and then you have a nerve toxin that quite easily crosses the blood-brain barrier.

      lead’s bad for you, sure, but when some of the other metals on this scale’s red might literally explode your tongue/face/head depending on sample size and saliva accumulation, i’d say yellow fits it pretty well.

    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 water 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.

    Beryllium is mostly only toxic when you breathe it in (there’s even a special disease you get from it), but as a solid, it’s pretty safe afaik.

    Not that I recommend it.

    i’m not a chemist but is this licking the most common molecule form or the atomic variety

    O₂ is safe but i don’t think O is

      I think it’s framed in the context of: “How dangerous would a single molecule be to a human?”. In that context, I would say O is safe, only because our body naturally destroys the radical oxygen molecules every day that we create with our anti-oxidants.

      True, in a larger quantity than our body can handle, it’s extremely toxic; but a single molecule would probably not be too bad.

      But I do agree, it shouldn’t be Green. It should be Yellow at least.

        O would completely destroy you in lickable quantities. I think you underestimate how extremely reactive it is. Just remember that it is so reactive that it reacts with oxygen to form ozone. This is not a little byproduct in extremely small quantities all throughout the body, which is also not the O radical anyway.

      If someone’s licking any of the transuranic elements I’m not sticking around to watch.

      Some stuff should simply not exist in a lickable quantity.

      I see we’re continuing the trend of scaring literally everyone when a scientist gets excited.
