Thorium has 90 protons, 142 neutrons, and 90 electrons.
Thorium protons
- Protons = atomic number
From the periodic table, find the atomic number of thorium.
The atomic number of thorium is 90. Hence, thorium has a total of 90 protons.
Thorium neutrons
- Neutrons = atomic mass – atomic number
The atomic mass of thorium is 232.03806, so we’ll take the roundup value as 232. And the atomic number of thorium is 90.
Subtract the atomic number (90) from the atomic mass (232). Hence, thorium has a total of 232 – 90 = 142 neutrons.
Thorium electrons
- Electrons = atomic number
The atomic number of thorium is 90. Hence, thorium has a total of 90 electrons.
