The first electron shell can hold up to 2 electrons, the second shell can hold up to 8 electrons, and the third shell can hold up to 18 electrons. Therefore, a total of 28 electrons are needed to fill the first three electron shells.
The number of electrons in any given shell can be represented by 2n2, where n = the shell number. In the first shell, there can be 2 electrons.

How many number of shells in sodium?
Sodium has 3 electron shells. The first shell can hold up to 2 electrons, while the second and third shells can hold up to 8 electrons each. Sodium has 11 electrons in total.
How many electron shells does an atom of oxygen have?
An oxygen atom has two shells. The first contains two electrons, and the second contains six electrons.
Why Two electron shells in oxygen?
Oxygen has two electron shells because it has eight electrons. The first shell can hold a maximum of two electrons, while the second shell can hold up to eight electrons. In oxygen, two electrons occupy the first shell and the remaining six electrons occupy the second shell to satisfy the octet rule.
