Question

Which subshell is the highest energy subshell?

• A. s - sub shell
• B. p - sub shell
• C. d - sub shell
• D. f - sub shell

Answer 1

The correct option is D f - sub shell

f subshell is the highest energy subshell which can hold upto 14 electrons. s subshell is the lowest energy subshell which can hold upto 2 electrons, p and d subshells lie after s in the increasing order where p and d can hold 6 and 10 electrons respectively.
So the energy of the subshells in the increasing order is
s < p < d < f.
