Answer :

The Lewis structure of [tex]AsH_3[/tex] shows 1 non-bonding electron pair on as.

Explanation :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

The given molecule is, [tex]AsH_3[/tex]

As we know that arsenic has '5' valence electrons and hydrogen has '1' valence electron.

Therefore, the total number of valence electrons in [tex]AsH_3[/tex] = 5 + 3(1) = 8

According to Lewis-dot structure, there are 6 number of bonding electrons and 2 number of non-bonding electrons.

The Lewis-dot structure of [tex]AsH_3[/tex] is shown below.
