Question

The two electrons have the following set of quantum numbers:
$P=3,2,-2,+\frac{1}{2}$
$Q=3,0,0,+\frac{1}{2}$
Which of the following statement is true?

• A. $P$ and $Q$ have same energy
• B. $P$ has greater energy than $Q$
• C. $P$ has lesser energy than $Q$
• D. $P$ and $Q$ represent same electron

Answer 1

Answer: (B)

$P$ has greater energy than $Q$

$P$ has greater energy than $Q$ as the $l$ value $P$ is greater than $Q$ and the energy is given by $(n+l)$ value.
