Book Free DemoDefine valency by taking examples of silicon and oxygen.
Valency or valence refers to an atom's ability to a pair of electrons to form a chemical compound.
Oxygen:
Atomic number of oxygen \(=\) \(8\)
Electronic configuration of oxygen \(=\)
In oxygen atom, the valence electrons are . To fill the orbit, electrons are required. Hence, the valency of oxygen is .
Silicon:
Atomic number of silicon \(=\) \(14\)
Electronic configuration of silicon \(=\)
In the silicon atom, the valence electrons are . To fill this orbit, electrons are required. Hence, the valency of silicon is .
