MCQ
The first four ionization energy values of an element are $191, 578, 872$ and $5962 \,k\,cal$. The number of valence electrons in the element is
  • A
    $1$
  • B
    $2$
  • ✓
    $3$
  • D
    $4$
✓

Answer

Correct option: C.
$3$
c
(c) Since the $IV$, $I.E.$ is very high. Thus electron is to be removed from stable configuration.
