What is a covalent bond?
ChemistryBonding
Quick Answer
A covalent bond is a chemical bond where atoms share one or more pairs of electrons. It is common between nonmetals.
The Full Story
Covalent bonding occurs when atoms share electrons to fill their outer shells and become more stable. This kind of bond holds together many familiar substances, including water, carbon dioxide, methane, and DNA. Single, double, and triple covalent bonds differ in how many electron pairs are shared. The idea became a major part of modern chemistry in the early 20th century, especially through the work of Gilbert N. Lewis. Covalent bonding explains much of molecular shape and chemical behavior.
Key Facts
1.Water molecules contain covalent bonds
2.Lewis proposed the electron-pair model in 1916
3.Single, double, and triple bonds involve 1, 2, or 3 shared pairs
