Question

Please Help! Which material undergoes radioactive decay? A) all elements that have a half-life B) all elements that contain atoms with protons C) all elements that have turned into a new element D) all elements that have a consistent number of particles Thanks!

Answer 1

Answer: C

Proof: This would be C because radioactive decay is when atoms and protons decide to slowly decay or separate from the atom. Therefore, they would produce radiation. Just like atomic bombs or nuclear waste. (Hope this helps-)
