Determine the number of valence electrons in pcl₃ and then draw the corresponding lewis structure.
Nikolay [14]

The number of valence electrons in PCl_{5} will be 26.

The atom's outermost inhabited shell is where valence electrons are found. They are significant because they have a major impact on how an atom's chemical characteristics are determined.

The number of valence electron in P in 5 and number of valence electron in Cl is 7. There are one molecule of P and three molecule of Cl in  PCl_{5}  molecule. By adding all valence electrons , the total number of valance electrons will be 26.

The Lewis structure of  PCl_{5}  is shown as:

Therefore, the number of valence electrons in PCl_{5} will be 26.

2

Explanation:

Mechanical Advantage (M.A) = Load/Effort....................................... (1)

Load = 10 N

Effort =  5 N

So substituting into equation (1), we have :

M.A =  10 N/5 N

       =  2
