Calcium has 20 protons, 20 neutrons, and 20 electrons.
Calcium protons
- Protons = atomic number
From the periodic table, find the atomic number of calcium.
The atomic number of calcium is 20. Hence, calcium has a total of 20 protons.
Calcium neutrons
- Neutrons = atomic mass – atomic number
The atomic mass of calcium is 40.078, so we’ll take the roundup value as 40. And the atomic number of calcium is 20.
Subtract the atomic number (20) from the atomic mass (40). Hence, calcium has a total of 40 – 20 = 20 neutrons.
Calcium electrons
- Electrons = atomic number
The atomic number of calcium is 20. Hence, calcium has a total of 20 electrons.
