MCQ
Which of the following is the correct electronic formula of chlorine molecule
  • $:\,\mathop {Cl}\limits_{.\,.}^{\,\,\,.\,.} \,:\,\mathop {Cl}\limits_{.\,.}^{\,\,\,.\,.} \,:$
  • B
    $:\,\mathop {C{l^ - }}\limits_{.\,.}^{\,\,\,.\,.} \,:\,\,:\,\,\mathop {C{l^ + }}\limits_{.\,.}^{\,.\,.} \,:$
  • C
    $:\,\mathop {Cl}\limits_{}^{\,\,\,.\,.} \,:\,\mathop {Cl}\limits_{}^{\,\,\,.\,.} \,:$
  • D
    $:\,\mathop {Cl}\limits_{}^{\,\,\,.\,.} \,:\,\mathop {\,:\,Cl}\limits_{}^{\,\,\,.\,.} \,:$

Answer

Correct option: A.
$:\,\mathop {Cl}\limits_{.\,.}^{\,\,\,.\,.} \,:\,\mathop {Cl}\limits_{.\,.}^{\,\,\,.\,.} \,:$
(a) $:\mathop {\mathop {Cl}\limits^{..} }\limits_{..} \, \cdot \, \cdot \mathop {\mathop {Cl}\limits^{..} }\limits_{..} :$ is the correct electronic formula of $C{l_2}$ molecule because each chlorine has $7$ electrons in its valence shell.
