What is the maximum number of electrons in an s subshell?

Explanation:
The maximum number of electrons in an s subshell is 2. This is because the s subshell consists of a single orbital. An orbital can hold a maximum of two electrons, which must have opposite spins according to the Pauli exclusion principle. Therefore, regardless of the energy level, any s subshell (whether it is 1s, 2s, 3s, etc.) can always accommodate only two electrons. Other subshells, such as p, d, and f, have more orbitals and can hold more electrons, but the s subshell remains limited to just the two electrons.
