Sodium has 11 protons, 12 neutrons, and 11 electrons.
Sodium protons
- Protons = atomic number
From the periodic table, find the atomic number of sodium.
The atomic number of sodium is 11. Hence, sodium has a total of 11 protons.
Sodium neutrons
- Neutrons = atomic mass – atomic number
The atomic mass of sodium is 22.989769, so we’ll take the roundup value as 23. And the atomic number of sodium is 11.
Subtract the atomic number (11) from the atomic mass (23). Hence, sodium has a total of 23 – 11 = 12 neutrons.
Sodium electrons
- Electrons = atomic number
The atomic number of sodium is 11. Hence, sodium has a total of 11 electrons.
