# Which energy level does not have a p-orbital ?

According to quantum principles,

Each energy level (Denoted by n) contains subshells (Denoted by

*l*).

The value of

*l*assumes all the value that lie in the range of 0 to n-1.

*l*= 0 ---------- s subshell

*l*= 1 ---------- p subshell

*l*= 2 ---------- d subshell

*l*

*=*3 ---------- f subshell

For n=1 i.e for the first energy level, the value of

*l*cannot be one according to the above mentioned rule, Hence p subshell is not possible and hence no p orbital can be present in n=1 energy level.

Hope this helps,

Regards
