(a) If one subshell of an atom has 9 electrons in it, what is the minimum value of l ? (b) What is the spectroscopic notation for this atom, if this subshell is part of the n = 3 shell?

To determine

(a)

The minimum value of l if one subshell of an atom has 9 electrons in it.

Explanation

Given Data:

Given one subshell of an atom has 9 electrons in it.

Formula Used:

Number of electrons in a shell is given as

n=2(2l+1)

Where n= number of electrons

l= angular momentum quantum number

Calculation:

Given that one subshell of an atom has 9 electrons in it

Case 1: For l=1

We have

n=2[2(1)+1]

n=2[2+1]<

To determine

(b)

The spectroscopic notation for this atom, if this subshell is part of the n=3 shell.
