The s orbital holds one subshell which is capable of housing two electrons.

The s orbital represents the elements of the first two columns of the periodic table.

The Alkali Metals is the first column and have an electron valence shell of $s^{1}$ $s^1$ .

Lithium - Li $1 s^{2} 2 s^{1}$ $1s^2 2s^1$
Sodium - Na $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{1}$ $1s^2 2s^2 2p^6 3s^1$
Potassium - K $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 4 s^{1}$ $1s^2 2s^2 2p^6 3s^2 3p^6 4s^1$

The Alkaline Earth Metals is the 2nd column and have an electron valence shell of $s^{2}$ $s^2$ .

Beryllium - Be $1 s^{2} 2 s^{2}$ $1s^2 2s^2$
Magnesium - Mg $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2}$ $1s^2 2s^2 2p^6 3s^2$
Calcium - Ca $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 4 s^{1}$ $1s^2 2s^2 2p^6 3s^2 3p^6 4s^1$
