what is the cohalent bond and their properties
Answers
Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to ionic compounds.
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.
Types of Covalent Bonds
Depending upon the number of shared electron pairs, the covalent bond can be classified into:-
- Single Covalent Bond
- Double Covalent Bond
- Triple Covalent Bond
