Hydrogen number one on the periodic table is on the left side and is a non metal gas.

Hydrogen is on the left side because like members of the IA group containing Lithium, Sodium and Potassium it has a normal charge of +1.

Hydrogen is a non metal because it does not form metallic bonding. It has a medium electronegativity not a low electronegativity like most metals. Hydrogen is not a conductor, is not malleable.

Hydrogen is a gas, most metals are solids except for mercury.
