Question

what is the formula of formal charge

Answer 1

However, since the “number of bonding electrons divided by 2” term is also equal to the number of bonds surrounding the atom, here's the shortcut formula: Formal Charge = [# of valence electrons on atom] – [non-bonded electrons + number of bonds]. Let's apply it to some examples. for example BH4 (top leftcorner)

Answer 2

Hey,this is answer!!!

Formal charge=[# of valence electrons]-[electrons in lone pairs +1/2 the number of bonding electrons]

Hope that this ans will help u!!!!
