Um... potassium is reactive, not radioactive.

Nope, it's also slightly radioactive. in fact you absorb more radiation eating a banana than you would in a day living within a 10 miles of a nuclear power plant

Chernobyl? Fukushima? I'll stick to bananas. :)

An isotope of potassium - potassium 40 - decays into argon. Potassium-argon is one of the more widely used methods to date rocks, along with Sr-Rb and U-Pb. In fact, carbon dating is a particularly poor way to date rocks (too old, no carbon). It is a very good way to date organic material that's typically much younger than rocks.

K-40 is a common radionuclide as others have pointed out but to another point, bananas aren't uniquely rich in potassium - potatoes have more, for example

Grantdon's right, the convention is to spell it 'aluminium', in line with most other elements, but the bloke who discovered it called it 'aluminum'.

I just learned about using lithium in mood stabilizer drugs in psychology last week.

I read somewhere that if you're worried about the harmful effects of banana radiation then you needn't worry since one would have to eat something like 15 million bananas for there to be any effect of radiation, and you'd likely die of indigestion long before that!

Made a guess that the "poison of kings" was polonium.

My brain: "Am I misspelling it?? It's, like, Shakespearean, right? Hamlet? Didn't Hamlet use polonium? Wait. Polonius. Polonius is a character in Hamlet. Ok, time to go to sleep."

"Strength-to-weight" should be hyphenated, especially if you're not going to follow it with "ratio".

Hemlock is the ‘poison of kings’ whereas arsenic is the ‘king of poisons’.

I like these quizzes, but #2 copied a lot of the same elements as #1. And some of the repeats were arguably easier. Maybe switch it up more in terms of difficulty and new elements.

I kept trying "uranium" and "neptunium" for "One of the planets". I got confused by my native language in which the names of these elements are exactly the same as names of Uranus and Neptune but mercury sounds nothing like Mercury.

You mean venomous, not poisonous. Poisonous refers to something that is eaten or inhaled, like a poisonous mushroom. Venomous is something that can deliver poison, like a venomous snake.

I spent ages trying americium for the radioactive gas in basement cause americium is used in smoke alarms as it decays and emits radiation
