# formal charge

Furthermore, for any element, converting a lone pair into a covalent bond changes the formal charge by plus one. Converting a covalent bond into a lone pair

MINUS FORMAL CHARGES ON MORE ELECTRONEGATIVE ELEMENTS ARE GENERALLY MORE STABLE THAN MINUS FORMAL CHARGES ON LESS ELECTRONEGATIVE ELEMENTS

The formal charges computed for the remaining atoms in this Lewis structure of carbon dioxide are shown below.

Calculating formal charges

Here's a question. Alkanes, alkenes, and alkynes are neutral, since there are four bonds and no unbonded electrons: 4 – [4+0] = 0.

It is important to keep in mind that formal charges are just that – formal, in the sense that this system is a formalism. The formal charge system is just a
