whar's 'ion charge"

Answer 1

Ion charge refers to the electric charge of an ion, which is a particle that has lost or gained one or more electrons and has thus become positively or negatively charged. The ion charge is the amount of positive or negative charge carried by an ion, and it is expressed in terms of the number of electrons lost or gained. For example, a sodium ion (Na+) has a single positive charge because it has lost one electron, while a chloride ion (Cl-) has a single negative charge because it has gained one electron.
