Notice that the positions of the lone pairs on the O atom are automatically adjusted when the second pair is added. In the structure below, the terminal oxygen atom with a complete octet must have a formal charge of -1. To draw a bond with an element other than carbon at the other end:Note This can only be done with single bonds, but you can edit the bond later. You structure should look like this.
