What is the most dangerous element on the periodic table and why?
You can think of plutonium as the radioactive big brother to the other heavy metals. It’s poisonous on its own, plus it floods its surrounds with alpha, beta, and gamma radiation. It’s estimated that 500 grams of plutonium if inhaled or ingested, could kill 2 million people.
What is the most radioactive thing on the periodic table?
Polonium
Polonium. Because it is a naturally-occurring element that releases a huge amount of energy, many sources cite polonium as the most radioactive element.
