Valence (chemistry)
Valence (Chemistry)
Valence (pronounced: /ˈvæləns/), in Chemistry, refers to the combining power of an Atom to form chemical bonds with other atoms. The term originates from the Latin word valentia, meaning "strength" or "capacity".
Etymology
The concept of valence was first introduced in the mid-19th century by Sir Edward Frankland, a British chemist. The term "valence" is derived from the Latin word valentia, which means "strength" or "capacity". This term was used to describe the bonding capacity of an atom, which is determined by the number of electrons it can lose, gain, or share when forming a chemical bond.
