Question

Different energy level for subshell?​

Answer 1

Answer:

They are the different kinds of orbital. So in the first shell there is only one subshell, the s orbital. It is called 1s. In the second shell there are s and p orbitals

Explanation:

Electrons are placed into available shells, starting with the lowest energy level. Each shell must be full before the next starts to fill. This model breaks down at the n=3 shell because each shell has subshells. There are 4 subshells, s, p, d, and f.

The s subshell is the lowest energy subshell and the f subshell is the highest energy subshell.
