Answer 1

1. Element - a. An atom with a unique number of protons
2. Photon - c. A bundle or quantum of light
3. Isotopes - d. Atoms with same atomic number but different mass numbers
4. Nuclear fission - b. Splitting of an atom into two or more parts

Answer 2

Step-by-step explanation:

According to question

Element : An atom with a unique number of protons.

A pure substance which consist of only one kind of atoms

Photon : A bundle or quantum of light.

Photon is elementary particle. light is moved over a space by photon.

Isotopes : Atoms with same atomic number but different mass number

Isotopes are two atoms having same atomic number but different mass number.

Nuclear fission: Splitting of an atom into two or more parts.

When a large atomic nucleus splits into smaller nuclei it is called nuclear fission.
