Electrons move in orbits (called shells) around the nucleus like the planets around the sun. You can notice that each shell can only hold a certain number of electrons:

the first shell (close to the nucleus) cannot hold more than 2 electrons,

the second shell not more than 8,

the third shell not more than 18,

the fourth shell not more 32,
