Hydrogen is different from other elements in column 1 (also known as Group 1 or the alkali metals) because it is not an alkali metal itself. It is actually a nonmetal and is placed above Group 1 in the periodic table due to its unique characteristics.
Here are some key differences:
1. Electronic configuration: Hydrogen has its own electronic configuration, with one electron in its only shell. In contrast, the alkali metals in Group 1 have one electron in their outermost shell.
2. Metallic properties: The alkali metals in Group 1, like lithium, sodium, potassium, etc., exhibit typical metallic properties such as high electrical conductivity, malleability, and ductility. Hydrogen, on the other hand, is a nonmetal and does not possess such metallic characteristics.
3. Reactivity: Alkali metals in Group 1 are highly reactive, readily losing their outermost electron to form +1 cations. Hydrogen can also be reactive, but it behaves differently than alkali metals. It can either gain or lose an electron, forming positive or negative ions, or it can simply share electrons through covalent bonding.
4. Physical state: Hydrogen is found as a gas at room temperature and pressure. Alkali metals are solid elements, with various melting and boiling points.
Overall, hydrogen differs from the other elements in Group 1 due to its nonmetallic nature, distinct electronic configuration, unique reactivity, and its physical state as a gas instead of a solid.
