Question

what is....... .............
condition for covalent bond​

Answer 1

${\underline{\underline{\red{\bf{\dag Covalent\:Bond \dag :}}}}}$

• The bond formed between two nonmetal atoms by equal sharing of electrons is called Covalent bond.
• It is formed when two atoms attain their nearest noble gas configuration by sharing one or more electron pairs .
• Each atom contributes equal number of electrons towards the bond formation.
• For ex - The bond between two oxygen atoms ( $\sf{O_2}$) is covalent bond .

$\small{\underline{\purple{\bf{\leadsto Conditions \: required:}}}}$

• Each of the atoms should have 4,5,6 or 7 atoms in their Valence shells.
• Two electrons are required to form a bond.
• There must be a maximum of eight electrons in the valence shell for the majority of molecules.
• The bonds will be formed in such a way that repulsion between electrons should be minimum.
• There must be overlap of atomic orbitals:
