Explanation:

1. Ca  → element

Ca is a symbol of calcium element categorize as alkali earth metal.

2.  → compound

Compound is a substance made up of two more than two different elements.

3. Nuclear decay  → fission

Fission is defined as process in which heavier unstable nucleus divide itself into two or more smaller stable nuclei with release of large amount of energy.

4. Nuclear synthesis  → fusion

Fusion is defined as process in which two or more nuclei combines together to form an larger nucleus with release of large amount energy.

5. η  → neutron

One of the subatomic particle of an atom located in the nucleus of an atom with no electrical charge.

6. Positive charge  → proton

One of the subatomic particle of an atom located in the nucleus of an atom with positive electrical charge.

7. e  → electron

One of the subatomic particle of an atom located inside an atom and outside the nucleus of an atom with negative electrical charge.

8. Number of protons in nucleus → atomic number

Atomic number of an atom is equal to the total number of protons present in the nucleus if the an atom.
