Answer : The number of valence electrons present in chlorine is, 7
Explanation :
Lewis-dot structure : It is also known as electron-dot structure. Lewis-dot structure shows the bonding between the atoms of a molecule and it also shows the number of unpaired electrons present in the molecule. The number of valence electrons are shown by 'dot' in the structure.
The given molecule is, chlorine
As we know that the chlorine belongs to group 17 that means it has 17 electrons.
The electronic configuration of chlorine is,
[tex]1s^22s^22p^63s^23p^5[/tex]
From this we conclude that the number of valence electrons present in chlorine is, 7
The Lewis-dot structure of chlorine is shown below.
