What is the minimun subshell

QUESTION

(a) What is the minimum value of l for a subshell that contains 15 electrons?
(b) If this subshell is in the n=5 shell, what is the spectroscopic notation for this atom?



Answer

A. l = 4, The minimum value of l for a subshell that contains 15 electrons and can take a
maximum value of 18 electrons.

B.spectroscopic notation: 5g15( n = 5)



Explanation

A.
l = 0 (s-subshell) can take maximum 2 electrons
l = 1 (p-subshell) can take maximum 6 electrons
l = 2 (d-subshell) can take maximum 10 electrons
l = 3 (f-subshell) can take maximum 14 electrons
l = 4 (g-subshell) can take maximum 18 electrons
l = 5 (h-subshell) can take maximum 22 electrons.
The minimum value of l for a subshell that contains 15 electrons is l = 4

B.
Since I = 4, it is in the g- subshell
spectroscopic notation: 5g15( n = 5, l = 4)
