Formation
|
A covalent bond is formed between two non-metals
that have similar electronegativities. Neither atom is "strong"
enough to attract electrons from the other. For stabilization, they share
their electrons from outer molecular orbit with others.
|
An ionic bond is formed between a metal and a
non-metal. Non-metals(-ve ion) are "stronger" than the metal(+ve
ion) and can get electrons very easily from the metal. These two opposite
ions attract each other and form the ionic bond.

What is it?
|
Covalent bonding is a form of chemical bonding between
two non metallic atoms which is characterized by the sharing of pairs of
electrons between atoms and other covalent bonds.
|
Ionic bond, also known as electrovalent bond is a
type of bond formed from the electrostatic attraction between oppositely charged
ions in a chemical compound. These kinds of bonds occur mainly between a
metallic and a non metallic atom.
