WebApr 8, 2024 · Formal Charge = (number of valence electrons in neutral atom)- (non-bonded electrons + number of bonds) Example 1: Take the compound BH4 or tetrahydrdoborate. Boron (B) possesses three valence electrons, zero non-bonded electrons, and four bonds around it. This changes the formula to 3- (0+4), yielding a result of -1.
