WebFormal Charge (FC) = (# of valence electrons) – (½) (number of bonded electrons) – (number of unbonded electrons) Examples: NH 3: what is the formal charge on the nitrogen? Nitrogen has 5 valence electrons, 6 bonded electrons (as there are 3 single bonds, each containing 2 electrons), and 2 unbonded electrons in this configuration. Thus: Web30 de abr. de 2024 · For a single charge, write - or + instead of 1- or 1+. In the example, the hydroxide ion is expressed as OH^-. Draw the Lewis Structure of the Ion Write each atom in the ion with its Lewis dot …
