Question #148321
How many orbitals are contained in any energy level?
Expert's answer
In each energy level, corresponding to the principal Quantum Number = n, there are total of (n+1) secondary quantum number(l) as
For principal Quantum Number = n
Secondary quantum numbers are
l = 0 , 1, 2, ......n
Each secondary quantum numbers correspondence to a orbital.
As for l = 0 it's "s" orbital
l = 1 it's "p" orbital
l = 2 it's "d" orbital
...................etc.
As (n+1) number of secondary quantum numbers are possible and each quantum numbers correspond to a specific orbital, so there are (n+1) number of orbitals in any energy level.
