Q6 / 180 · COMEDK 2016 · Chemistry

The number of $2 p$ electrons having spin quantum number $s=-1 / 2$ are

  • A
    2
  • Correct answer
    B
    3
  • C
    6
  • D
    0

Solution

The $2 p$-orbital has electronic configuration as follows
Figure
$\therefore$ Three electrons are with $-1$ / 2 spin quantum number and other three electrons are with $+1 / 2$ spin quantum number.

Hence, the correct answer is option: 'B'.
