Heya mate...❤❤

1. In chemistry, the valence or valency of an element is a measure of its combining power with other atoms when it forms chemical compounds or molecules. The concept of valence was developed in the second half of the 19th century and helped successfully explain the molecular structure of inorganic and organic compounds.
2. weMetals have Valency -1,2,3,4.......They have this valency so that they can loose electron and become positive charge.And Nonmetals have Valency-5,6,7,8....They have this valency so that they can gain electron and become negative charge......
