Draw the structure of CO32-. Include all lone pairs of electrons.
Draw the ion by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons. Use square brackets to denote the overall charge.
An oxyanion is a polyatomic ion that contains oxygen and has a net negative charge. Examples are SO42- , NO3- , and CO32-
In many oxyanions, the oxygen atoms form one single bond with three lone pairs, giving them each a formal charge of − 1. O- However, if this bonding arrangement does not give the central..
atom an octet of electrons, multiple bonds form between the central atom and one or more of the outer oxygen atoms. An oxyanion may combine with a cation to form an ionic compound. Examples are K2SO4, NaNO3, and CaCO3.
