Question

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

Answer 1

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

Step-by-step 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.
