Answer :
An atom has 5 valence electrons that in a compound has 8 bonding electrons and 0 lone pair electrons. The formal charge of this atom is: +1.
What is the formal charge?
The formal charge is a formula that counts an atom’s electrons to note its role in the molecule.
To find the formal charge in an atom, we can use the equation below:
Formal charge = valence electrons – Σ lone pair electrons – ½ Σ bonding electrons
Formal charge = 5 – 0 – ½ (8)
Formal charge = 5 – 4
Formal charge = 1
Hence, the formal charge of the atom is +1.
