Francium has 87 protons, 136 neutrons, and 87 electrons.
Francium protons
- Protons = atomic number
From the periodic table, find the atomic number of francium.
The atomic number of francium is 87. Hence, francium has a total of 87 protons.
Francium neutrons
- Neutrons = atomic mass – atomic number
The atomic mass of francium is 223 and the atomic number of francium is 87.
Subtract the atomic number (87) from the atomic mass (223). Hence, francium has a total of 223 – 87 = 136 neutrons.
Francium electrons
- Electrons = atomic number
The atomic number of francium is 87. Hence, francium has a total of 87 electrons.
