Question

How many sub shells are possible for n=2?
​

Answer 1

Answer:

The number of values of the orbital angular number l can also be used to identify the number of subshells in a principal electron shell: When n = 1, l= 0 (l takes on one value and thus there can only be one subshell) When n = 2, l= 0, 1 (l takes on two values and thus there are two possible subshells)
