Answer the following question:
Define valency by taking example of fluorine.
Valency or valence refers to an atom's ability to to form a chemical compound.
Example:
Atomic number of fluorine \(=\) \(9\)
Electronic configuration of fluorine \(=\)
In fluorine atom, the valence electrons are . To complete its octet, electrons are required. Hence, the valency of fluorine is .
