Question

define covalent bond?​

Answer 1

Answer:

#What are Covalent Bonds?

Elements having very high ionisation energies are incapable of transferring electrons and elements having very low electron affinity cannot take up electrons. The atoms of such elements tend to share their electrons with the atoms of other elements or with other atoms of the same element in a way that both the atoms obtain octet configuration in their respective valence shell and thus achieve stability. Such association through sharing of electron pairs among different or same kinds is known as Covalent Bond.

#Covalent Bonding can be Achieved in two Ways:

1) Sharing of electrons between atoms of the same kind E.g. Formation of H2, Cl2, O2, etc.

2) Sharing of electrons between atoms of different kind E.g. Formation of CH4, H2O, NH3, etc.
