    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.

      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.

    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.

    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.

      It is. Activated carbon is used to treat diarrhoea, you basically swallow a chunk of carbon that absorbs any moisture it comes across

        Don’t lick carbon nano tubes or buckyball. Also in general carbon powder can be a particulate inhalation issue.

          The table is about licking specifically. It’s not a breathability table. Just so that is clear.

            I assume if it’s getting anywhere near your mouth you’d also be breathing it but aside from that, ingestion is also a nogo.

              The ingestion/breathability table might be more restrictive. Like, elemental Sulfur is perfectly fineno actually it’s not fine— but probably unpleasant to lick. Contact dermatitis likely but not life threatening—just one lick, ok; promise no more? ;)

              Breathing elemental Sulfur is also going to result in contact dermatitis -inside the lungs. Which is going make a really bad day.

        Not moisture but reactive molecules. (I mean, many forms probably do still absorb a good bit but) I forgot the exact chemistry but “activated” means chemically reactive. It binds with all sorts of reactive molecules, like toxins and many other things.

    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.

    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).

        Given the choice between licking mercury and licking lead, 96% of respondents answered with lead.

        Apologies for the random percentage and quoting fictional data.

          It isn’t safe at any dose but the amount of harm from licking it once is definitely rather small. Probably safer than having a couple of alcoholic drinks or a single cigarette.

          The inside of your mouth is on the outside of your body and so is the rest of your digestive tract, safely (well) isolated (unless it’s permeable) from your bloodstream. As a first approximation, our bodies are toruses. Just licking something is really not much more intimate than touching something unless it’s sugar which can be taken up right there on the spot. (At least glucose can and there’s enzymes in salvia don’t ask me for details).

          All that said the Romans used lead(II) acetate as a sweetener and while definitely a bad idea, they didn’t all immediately keel over either. You’ll almost certainly be fine.

          Pure water OTOH… you’ll burn your mouth because osmotic pressure tearing cell walls apart before the stuff dilutes to have a sensible amount of minerals in it. The tissue there is used to sudden violent cell death and heals quickly so no biggie, if you survived a too hot pizza you’ll survive water. Also, do eat that pizza to have enough minerals to replenish everything.

    Metallic Mercury is absolutely no problem. They used it to treat congestion back in the day.
