The first shell in atoms contain one orbital only that can hold up to two electrons.

Explanation:

The first shell in atoms contain one orbital only that can hold up to two electrons.

The first energy level (shell) has the quantum number #n=1#.

Inside this shell you have the orbital #s#. This explains why all electron configuration of elements starts with #1s^2#.
