Each has a positive or negative charge that is spread among the nuclei and electron shells of the polyatomic ion. Hence the charge is present nowhere. Note: An anion is a negatively charged ion with more electrons than protons, whereas a cation is a positively charged ion with less electrons.
How do you find the charge of a polyatomic ion?
Calculate from Oxidation Number
The oxidation number of oxygen is -2, and the oxidation number of hydrogen is +1. Add together the oxidation numbers of all the atoms in the polyatomic ion. In the example, -2 +1 = -1. This is the charge on the polyatomic ion.
What does the charge on a polyatomic ion mean?
The charge on a polyatomic ion is equivalent to the number of electrons the parent molecule has lost or gained.
