Answer 2

Answer:

1. Neutron Number = 12

2. Mass Number = 14

3. Proton Number = 17

Explanation:

Neutron number: determined by subtracting the atomic mass and atomic number

Mass number: written on the top of the element. also named as "A"

Proton number: written at the bottom. called the atomic number, or "Z"
