Question

write difference between nuclear fission and radioactivity

Answer 1

nuclear fission means fission of nucleus and radioactivity meaning is the reactivity of an element

Answer 2

They are both forms of the same process, nuclear fission is usually referred to as the chain reaction created when when two unstable masses are held in close proximity for a split second creating what is known as a critical mass, Huge amounts of energy are released. Radioactivity is the natural decaying of an atom that is unstable because of a large surplus of neutrons in it's nucleus, radioactive energy is released as individual neutrons are ejected from the nucleus.
