Magnesium has 12 protons, 12 neutrons, and 12 electrons.
Magnesium protons
- Protons = atomic number
From the periodic table, find the atomic number of magnesium.
The atomic number of magnesium is 12. Hence, magnesium has a total of 12 protons.
Magnesium neutrons
- Neutrons = atomic mass – atomic number
The atomic mass of magnesium is 24.305, so we’ll take the roundup value as 24. And the atomic number of magnesium is 12.
Subtract the atomic number (12) from the atomic mass (24). Hence, magnesium has a total of 24 – 12 = 12 neutrons.
Magnesium electrons
- Electrons = atomic number
The atomic number of magnesium is 12. Hence, magnesium has a total of 12 electrons.
