Similarities with Halogens
- Diatomic Nature: Like halogens, hydrogen exists as a diatomic molecule (H₂).
- Covalent Bonds: Hydrogen forms covalent compounds with metals and non-metals, similar to halogens.
- Reactivity: Hydrogen reacts with halogens, oxygen, and sulfur, forming compounds with formulas similar to alkali metals.
Similarities with Alkali Metals
- Electronic Configuration: Hydrogen's electronic configuration resembles that of alkali metals.
- Ionic Forms: Hydrogen can form both positive ions (e.g., in HCl) and negative ions (e.g., in NaH), demonstrating dual behavior.
