Options:
A) $ :,\underset{.,.}{\overset{,.,.}{\mathop{Cl}}}:,\underset{.,.}{\overset{,.,.}{\mathop{Cl}}}: $
B) $ :,\underset{.,.}{\overset{,.,.}{\mathop{C{l^{-}}}}}::\underset{.,.}{\overset{,.,.}{\mathop{C{l^{+}}}}}: $
C) $ :,\underset{{}}{\overset{,.,.}{\mathop{Cl}}}:,\underset{{}}{\overset{,.,.}{\mathop{Cl}}}: $
D) $ :,\underset{{}}{\overset{,.,.}{\mathop{Cl}}}:,\underset{{}}{\overset{,.,.}{\mathop{,:,Cl}}}: $
Show Answer
Answer:
Correct Answer: A
Solution:
$ :\underset{..}{\mathop{\overset{..}{\mathop{Cl}},}}\cdot ,\cdot \underset{..}{\mathop{\overset{..}{\mathop{Cl}},}},: $ is the correct electronic formula of $ Cl_2 $ molecule because each chlorine has 7 electrons in its valence shell.
