The number of valence electrons in
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
molecule. By adding all valence electrons , the total number of valance electrons will be 26.
The Lewis structure of
is shown as:
Therefore, the number of valence electrons in
will be 26.
