You will observe that in our day to day work routine how much depends on computers. Almost all over the world, the utility bills (i.e. gas, electricity and telephone bills) are prepared by computers.

Ions | Types of Ions | How Ions Formed | Cations, Anions

Definition:                 A molecule, atom or species having a positive or negative charge is called an ion. Types of Ions.                      Ions are two types a) Positive Ions or Cations  b) Negative Ions or Anions a) Positive Ion or Cation:                                          A species which has a positive charge is called positive ion Cation. When atoms lose one or more electrons, positive ions are formed. A sufficient amount of energy is supplied to a neutral atom, then the atom loses an electron to form a positive ion. For this reason, the formation of a positive ion is an endothermic process.         A     + Energy ---------------------> A     +    1e  =  +ve Cations may have +1, +2, +3, +4 charge...
