Question

What is the valency of fluoride?

Answer 1

Valency

• The valency of an atom refers to its ability to combine with other atoms.
• The valency of an element determines the number of bonds that an atom can make as part of a complex.
• The electrons in the atom's outermost orbit are referred to as valence electrons.

Valency of fluoride

• The outermost shell of the fluorine atom has seven electrons.
• Because the charge of the fluoride ion is $-1$, its valency is regarded as $1$.
• The simplest inorganic, monatomic anion of fluorine with basic characteristics is ${\mathrm{F}}^{-}$, fluoride ion.

Hence the valency of fluoride is $1$.
