Answer:

see explanation

Explanation:

Given PH₃

Valence = P + 3H = 1(5) + 3(1) = 8 valence electrons

Bonded Substrates = 3H = 3(2) = 6 bonded electrons

Nonbonded Pairs = (V - S)/2 = 8 - 6 / 2 = 2/2 = 1 Nonbonded pair (or 1 free pr)

Lewis Structure => 3 Bonded Pr + 1 Nonbonded Pr => :N-(H)₃ => Pyrimidal Geometry. (See images below).

Answer : The Lewis structure of [tex]PH_3[/tex] is shown below.

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]PH_3[/tex]

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

Therefore, the total number of valence electrons in [tex]PH_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]PH_3[/tex] is shown below.
