Answer 2

Answer :  The Lewis structure of $AsH_3$ 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, $NOF$

As we know that nitrogen has '5' valence electrons, oxygen has '6' valence electrons and fluorine has '7' valence electron.

Therefore, the total number of valence electrons in $NOF$ = 5 + 6 + 7 = 18

According to Lewis-dot structure, there are 6 number of bonding electrons and 12 number of non-bonding electrons.

The Lewis-dot structure of $NOF$ is shown below.
