Is hydrogen a metal or non metal?

Answer: Because hydrogen has the same ns¹ electron configuration as the alkali metals, hydrogen is classified as a non-metal and is positioned above group in the periodic chart. It differs from the other alkali metals in that it creates cations (H⁺) more reluctantly than the others. The ionisation energy of hydrogen is 1312 kJ/mol, while that of lithium (the alkali metal with the highest ionisation energy) is 520 kJ/mol.

Hydrogen is occasionally put above the halogens in the periodic table since it is a non-metal and creates H^– (hydride anions). Hydrogen, like halogens, can also create H₂ dihydrogen. Hydrogen, on the other hand, is not the same as the halogens. The electron affinity of hydrogen is substantially lower than that of the halogens.
