CBSE - IX - Chemistry - Structure of the Atom
How do atoms share elctrons with each other?
Formation of Covalent Bond
- When both atoms in a reaction need to gain electrons to complete their octet, sharing of electrons takes place.
- Let us study how the Chlorine molecule is formed to understand the formation of covalent bond.
Formation of Chlorine Molecule
- A Chlorine atom has seven electrons in the outermost shell.
- When two Chlorine atoms combine, they share one electron each to form a shared pair of electron, thus completing both their octets. Hence, the Chlorine molecule exists as Cl2.
