and how do we say that an element is the most radioactive one? is it the one that has got the least half- life period? Our chemistry teacher said that it is radium, somewhere it got the answer as polonium. if it is on the basis of half life then beryllium-8 should be most radioactive as it has a half- life of around 10^ -17 seconds plz explain.. thanks in advance Can a radioactive substance be any element of the periodic table? 10 points!?
Can it be any element as long as the nucleus is not stable.
