Explanation:

An ion is an atom or a group of atoms where the number of electrons is not equal to the number of protons . Electrons have a negative charge.

When an atom gains electrons this result in a negative charge . This type of ion is called an anion.

When an atom loses electrons this results in a position charge. A positively charged ion is called a cation .

EXAMPLES OF POSITIVE IONS :

  • Aluminium - Al 3 +
  • Barium - Ba 2 +
  • Bismuth - Bi 3 +
  • Cadmium -Cd 2 +l
