Question

NH3 P2O5 валентность

Answer 1

У азота 3
У фосфора 5

Answer 2

NH3 is the chemical formula for ammonia, and P2O5 is the chemical formula for diphosphorus pentoxide.

In ammonia (NH3), the nitrogen atom (N) has a valency (or valence) of 3, meaning it can form three chemical bonds.

In diphosphorus pentoxide (P2O5), the phosphorus atoms (P) have a valency of 5, meaning they can form five chemical bonds each.

It's important to note that valency refers to the combining capacity of an element or compound, and it is determined by the number of electrons an atom can gain, lose, or share when forming chemical bonds.
