Atoms can bond together in several different ways. name three types of chemical bonding. explain what happens to electrons in each type of bonding.

Atom can bond together either by  ionic bond, covalent bond, co-ordinate covalent bond.

Explanation:

a] The three types of chemical bonds are:

i) Ionic Bond

ii) Covalent Bond

iii) Co-ordinate Covalent Bond.

i) Ionic Bond: This bond happens between a metal and a non-metal due to electrostaic force which occur between two opposite charge ions. In this electron is given by electropositive atom to electronegative atom to gain positive charge. Eg: NaCl.

ii) Covalent Bond: Here, the electrons are shared among the two elements which can even be of the same species. Eg: Carbon-Carbon (C-C) covalent bond, N2.

iii) Co-ordinate Covalent Bond: It is a covalent bond between two atoms but unlike Covalent Bond, in this, the shared pair of electrons come from the same atom. Eg: The H+ in the NH4+ is attached to NH3 through a co-ordinate covalent bond.
