Hydrogen is a nonmetal and is placed above group in the periodic table because it has ns1 electron configuration like the alkali metals. However, it varies greatly from the alkali metals as it forms cations (H+) more reluctantly than the other alkali metals.

Hydrogen differs from alkali metals as it does not possess metallic character
Hydrogen, despite being placed in Group 1 of the periodic table along with alkali metals, is unique in its properties. One significant difference between hydrogen and alkali metals is that hydrogen does not possess metallic character, unlike alkali metals.
Reasons why hydrogen does not possess metallic character:
- Electron Configuration: While alkali metals have one electron in their valence shell, hydrogen has a unique electron configuration with only one electron. This results in hydrogen not exhibiting metallic properties like alkali metals.
- Chemical Behavior: Hydrogen can form compounds with non-metals, unlike alkali metals which typically form ionic compounds with non-metals. This further demonstrates the non-metallic character of hydrogen.
- Physical Properties: Unlike alkali metals which are shiny, soft, and have low melting points, hydrogen is a colorless, odorless gas at room temperature. Its physical properties are more akin to non-metals than to metals.
In conclusion, while hydrogen shares some similarities with alkali metals due to its position in Group 1 of the periodic table, it differs significantly by not possessing metallic character. This distinction is crucial in understanding the unique properties and behavior of hydrogen compared to alkali metals.
