MCQ
Two electrons $A$ and $B$ in an atom have the following set of quantum numbers 

$A : 3\,, 2\,, -2\,, +\, \frac{1}{2}$

$B : 3\,, 0\,, 0\,, + \,\frac{1}{2}$

What is true for $A$ and $B$

  • A
    $A$ and $B$ have same energy
  • $A$ has more energy than $B$
  • C
    $B$ has more energy than $A$
  • D
    $A$ and $B$ represent same electron

Answer

Correct option: B.
$A$ has more energy than $B$
b
$A$ has greater value of azimuthal quantum number $1$ which gives a greater energy value in a higher subshell.
