Barium has 56 protons, 81 neutrons, and 56 electrons.
Barium protons
- Protons = atomic number
From the periodic table, find the atomic number of barium.
The atomic number of barium is 56. Hence, barium has a total of 56 protons.
Barium neutrons
- Neutrons = atomic mass – atomic number
The atomic mass of barium is 137.27, so we’ll take the roundup value as 137. And the atomic number of barium is 56.
Subtract the atomic number (56) from the atomic mass (137). Hence, barium has a total of 137 – 56 = 81 neutrons.
Barium electrons
- Electrons = atomic number
The atomic number of barium is 56. Hence, barium has a total of 56 electrons.
