The lewis structure of ash3 shows nonbonding electron pair(s) on as.

Answer :

The Lewis structure of 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,

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

Therefore, the total number of valence electrons in = 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 is shown below.
