Question

Which orbital is the first to fill with electrons in a given principal energy level?

Answer 1

A: both d and f
B: s
C: f
D: p
E: both s and p



The corrrect answer here is E. (Both s and p) Hope this helps

Answer 2

The orbital which is the first to be filled with electrons in a given principal energy level is S orbital

Step-by-step explanation

s orbital is the first orbital in every energy level . Each orbital contain a maximum of two electron and according hund's rule every orbital in a subshell is singly with one electron before any one is doubled. Electron fill the lower energy level to higher energy orbital.
