The chemical element xenon is classed as a noble gas and a nonmetal.

What is the valency of phosphite?

Answer: Valency of P is 5, and valency of O is 2. Therefore, net valency of phosphate ion is 8-5=3,So Phosphate ion has 3 valency.

What metal is non-metal?


Physical property Metals Metalloids
Alkali, alkaline earth, lanthanide, actinide, transition and post-transition metals Boron, silicon, germanium, arsenic, antimony (Sb), tellurium
Form solid (Hg is liquid) solid
Appearance lustrous lustrous
Elasticity mostly malleable and ductile (Hg is liquid) brittle

What is valency of a non-metal?

The number of electrons accepted by a non metal is called valency of the non metal. For example, one atom of chlorine accepts 1 electron to form a negative chloride ion (Cl–), so chlorine is a non-metal.
