Answer 3

The valency (valence) of an element represents its ability to combine with other atoms to form chemical compounds. In the case of boron (B) in B2O3, the valency can be determined by analyzing the chemical formula of the compound.

In B2O3, there are two boron atoms (B) and three oxygen atoms (O). To form a stable compound, boron typically exhibits a valency of +3. Each boron atom in B2O3 contributes three valence electrons to form chemical bonds with the three oxygen atoms, resulting in a stable boron oxide molecule.

So, the valency of boron in B2O3 is +3.
