hydrogen is a metal or non-metal? does hydrrogen lose electrons or gain electrons ? give a brief description.

Hydrogen is accepted as a non-metal. One of the most common reason's for this is because Hydrogen is a gas (at room temperature). A statement that can invalidate this is, Mercury is a metal, but is a liquid (at room temperature). Experiments that justify Hydrogen's placement amongst the Alkali Metals include very low temperatures and very high pressures, at which Hydrogen acts like a metal, being more electrically and thermally conductive than silver.

Hydrogen lose electrons.
