Answer to Question #148321 in General Chemistry for Cindy Parmer

Question

How many orbitals are contained in any energy level?

Answer 1

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.
