MCQ
In argon atom how many electrons have $m_{\ell } = 1$ ?
  • $4$
  • B
    $2$
  • C
    $1$
  • D
    $6$

Answer

Correct option: A.
$4$
a
Argon has $18$ electrons

$A r(18)=1 s^2 \,2 s^2 \,2 p^6 \,3 s^2\, 3 p^6$

Value of $m_l \in(-l, l)$

where $l$ is aximuthat quantum number.

Total number of electrons for $m_l=1$ are $4$
