Ionic and Covalent Bonds | Science project | …

2 · Ions are defined as atoms having an electric charge as a result of losing or gaining one or more electrons. An ionic bond by definition is a chemical bond between a metal and a non metal in which electrons are transferred from one atom to another. In brief, in ionic bonding there is an exchange of electrons. One element giving up electrons and the
