What are the conditions necessary for the formation of covalent molecules?
Advertisements
उत्तर १
Covalent bond is formed when the participating atoms contribute one electron each to form an electron pair which is then shared by the participating atoms in such a manner that each atom attains the nearest noble gas configuration.
Each atom should not be completely filled before covenant bond formation.
उत्तर २
- Both atoms should have high electron affinity.
- Both atoms should have high ionization energy.
- Both atoms should have four or more electrons in their valence shells.
- Both atoms should have high electronegativity.
