[dropcap]I[/dropcap]In liquids, there are always a few particles with a lot of energy and some with very low energy. A small fraction of particles at the surface, having higher kinetic energy, is able to break away from …
Atoms are neutral; they contain the same number of protons (positive particles) and electrons (negative particles). When the numbers of these subatomic particles are not equal, the atom is electrically charged and is called an ion i.e. ions are electrically charged atoms with extra electrons or missing electrons. It means ions are formed when atoms lose or gain …
