Question

What is the maximum number of electrons having same spin with $n+l=4$?

• A. $3$
• B. $2$
• C. $4$
• D. $5$

Answer 1

Answer: (C)

Subshells with $n+l=4$ are $3p$ and $4s$

Value of $n$	Value of $l$	Value of $n+l$	Type of orbitals
$3$	$1$	$3+1$
$4$	$0$	$4+0$

Hence, maximum no. of electrons having same spin will be $4$
