formation of ions

IONIC COMPUND-

  • Are formed by the complete transfer of electron

  • They exist in solid state

  • metal + non metal

COVALENT COMPUND-

  • Are formed by the sharing of electrons between two atoms

  • They exist in solid, liquid, and gas state.

  • non metal + non metal OR metalloid + non metal

A chemical bond is a strong force of attraction linking atoms in a molecule or crystal.

Gilbert Lewis (1875-1946) discovered covalent compound

Ions are charged resulting from the loss or gain of one or more electrons from an atom or a molecule.

Cations form from the loss of electrons and have a positive charge

Anions form through the gain of electrons and have a negative
