Everything that isn't green should be 'definitely not' and several green ones are questionable
The particular form the element is in also matters a lot.
Take helium, for example. Is it really possible to 'lick' a gas? I'd say it's not. You could lick liquid helium, though ... and you really shouldn't, unless you enjoy severe frostbite on your tongue.
What? No. The Leidenfrost effect would apply. You could pour a few milliliters of liquid helium over your tongue and it would boil on contact. You just need to make sure to minimize total contact time.
if i stick my tongue out i would probably consider that as licking air, so you would just have to be submerged in that gas for a long enough time to lick it
You can totally lick Sodium! Its natures poprocks!
In theory, if you dry enough your tongue, you can lick sodium, i wouldn't keep it on my tongue longer tha 0.5s tho
well, i wouldn't keep it on my tongue at all tbf
Ok who gave the goat internet access?
It's 100% accurate. But just in case, could you have the map on you when you go around licking things? The resultant news article will be way funnier that way.
Sure! I'll keep that in mind for my next lickpacking tour across Europe.
Gonna have to vet the Blarney Stone before I lick it. Could be made out of anything.
Because everything exists in Europe :-D
Na: bad. Cl: bad. NaCl: amazing!
Pshh. You can lick any of them once.
You really shouldn't, though.

I can be, though, if you ask nicely..
Oganesson has a half-life of about 0.7 ms and is excruciatingly difficult to synthesize in a way that even lasts on the order of milliseconds. The beam it's created in is sent to a semiconductor detector. You'd be stretching the definition of "lick" very heavily if you could even convolute a way to make it land on the human tongue.
Easy, just send the beam to their tongue instead of the duperwhatsit detector. Bam. Licked.
If you can get your tongue inside the machinery they use at Lawrence Livermore to create a split-second instance of some rare Earth actinide, you deserve to lick it.
The periodic table is surprisingly lickable.
Coming from someone identifying as salt, that's high praise! 😁
It’s really funny, yesterday I saw a dude walk around with a T-shirt with exactly this periodic table and thought it was hilarious and now I find this
Did you lick him?
Can you lick a gas? I would think it would need to be at least liquid, and once some of these are in a lickable state you probably wouldn't want to go ahead and do it.
I’ve just licked some hydrogen
You dirty gasophile
why is it fine to lick calcium? wouldn't that cause sever burns?
It would, don't do it. There's more than one questionable assignment on the table including magnesium right above it.
If you find enough oganesson to lick, you should get to do it
I wouldn't advise licking calciums:
The chemistry of calcium is that of a typical heavy alkaline earth metal. For example, calcium spontaneously reacts with water more quickly than magnesium but less quickly than strontium to produce calcium hydroxide and hydrogen gas. It also reacts with the oxygen and nitrogen in air to form a mixture of calcium oxide and calcium nitride.[14] When finely divided, it spontaneously burns in air to produce the nitride. Bulk calcium is less reactive: it quickly forms a hydration coating in moist air, but below 30% relative humidity it may be stored indefinitely at room temperature.[15]
Because calcium reacts exothermically with water and acids, calcium metal coming into contact with bodily moisture results in severe corrosive irritation.[59] When swallowed, calcium metal has the same effect on the mouth, oesophagus, and stomach, and can be fatal.[46] However, long-term exposure is not known to have distinct adverse effects.[59]

Because of vigorous reaction of quicklime with water, quicklime causes severe irritation when inhaled or placed in contact with moist skin or eyes.
So.. I should lick it fast and then hide from the effects under a table?
If lead is "maybe not a good idea", the rest of these must be really bad ideas. I like that there's still 2 more levels above lead. I assume the second level just explodes or vaporises you instantly or something.
Licking lead once is completely fine, just don't make a habit of it
Can you lick a gas? Or do you have to cool it down until liquid?
I posted this a long time ago. Got sent Cody's Labs list, and it was very different. He has licked so many...

Technetium really should be purple. The isotope that you'd be most likely to get some of (used for nuclear medicine) has a half-life of about 6 hours, and is appropriately radioactive.
The good version of this says "see you on the other side".
How many licks to get to the center of a sodium lollipop
If you have enough saliva, just one...
Gas at room temperature? Probably not a good thing to lick when it is liquid nor solid.
Good luck finding enough Astatine to lick. It's the rarest naturally-occurring element on earth. It's estimated there is less than 30 grams in earth's crust at any given time.
I'm glad someone listened to me a couple years back. The first comment I ever made on Lemmy was on the original version of this, pointing out that Magnesium was DEFINITELY fine to lick.
I'm wearing that picture on a shirt right now!
😏 Are you a green element on the periodic table? Cause I wanna lick you
