Answer 1

Heya mate!!

In chemistry, the valence orvalency of an element is a measure of its combining power with other atoms when it forms chemical compounds or molecules. The concept ofvalence developed in the second half of the 19th century and helped successfully explain the molecular structure of inorganic and organic compounds.❤️

Answer 2

Answer:

Valency is the combining capacity of an element. For metals, it is equal to the number of electrons in the outermost shell of their atoms, and for nonmetals it is eight minus the number of electrons in the outermost shell. Transition metals like iron and copper show more than one valency in compound formation
