Ionic radius

The ionic radius is used to see how big or small the ions that atoms may make on their own.^[1] For instance, if the atom makes a positive ion by getting rid of one electron or more, the ionic radius would be smaller.^[1] The opposite is also true, so if the atom makes a negative ion by getting one electron or more, the ionic radius would be bigger.^[1]
