Covalent Bonding
Covalent bonding is the chemical bonding formed when atoms share one or more pairs of electrons.
Practice This ConceptMain explanation
Teacher explanation
Covalent bonds commonly form between non-metal atoms. Instead of transferring electrons completely, atoms share electron pairs so that each atom gets a more stable outer-shell arrangement.
Example
In a chlorine molecule, two chlorine atoms share one pair of electrons, so each chlorine atom completes its outer shell.
Simple analogy
Covalent means common sharing.
Common confusion
Students sometimes call every bond with non-metals weak. Covalent bonds within molecules can be strong, but forces between small molecules are often weak.
Exam tip
For covalent bonding answers, mention sharing of electron pairs and show shared electrons clearly in dot diagrams.
