Atomic Number: 1 | Atomic Weight: 1.008 | Category: Nonmetal | Ionization Energy: 1312 kJ/mol
Hydrogen is the lightest chemical element and most abundant in the universe. At room temperature, it's a colorless, odorless gas with strong reducing properties. Common Ions: H⁺ (hydrogen ion), H⁻ (hydride ion). Oxidation States: -1, +1. Hydrogen's ionization energy is a key reference for understanding atomic structure.
Atomic Number: 2 | Atomic Weight: 4.003 | Category: Noble Gas | Ionization Energy: 2372 kJ/mol
Helium is the second lightest element with extremely stable chemical properties, rarely forming compounds. Widely used in cryogenic research and as a protective gas. Oxidation States: 0 (forms no common ions). Helium's extremely high ionization energy reflects the chemical stability of noble gases.
Atomic Number: 3 | Atomic Weight: 6.94 | Category: Alkali Metal | Ionization Energy: 520 kJ/mol
Lithium is the lightest metal with very low ionization energy, easily losing electrons to form cations. Common Ions: Li⁺ (lithium ion). Oxidation States: +1. Li⁺ ions in lithium-ion batteries are central to modern energy storage technology.
