Hydrogen resembles both alkali metals and halogens. It can lose one electron like alkali metals and also gain one electron like halogens. Like halogens, it forms diatomic molecule and combines with metals and non-metals to form covalent compounds. Therefore, position assigned to hydrogen in the periodic table is considered anomalous.
