Radioactive decay is a ____ change.
A
nuclear
B
physical
C
chemical
D
none of these
Explanation: 

Detailed explanation-1: -Radioactive decay happens when an unstable atomic nucleus spontaneously changes to a lower-energy state and spits out a bit of radiation. This process changes the atom to a different element or a different isotope.

Detailed explanation-2: -There are three main types of nuclear reactions: Nuclear fusion: this is the joining of two small atomic nuclei into one nucleus. Nuclear fission: this is the splitting of one large atomic nucleus into smaller fragments. Radioactive decay: this is the change of a less stable nucleus to a more stable nucleus.

Detailed explanation-3: -Nuclear chemistry is the sub-field of chemistry dealing with radioactivity, nuclear processes, and transformations in the nuclei of atoms, such as nuclear transmutation and nuclear properties.
