Part 3. Survey of Period 1: hydrogen H to helium He. Period 1, the shortest period of the periodic table, only consists of two elements, hydrogen and helium. Although the properties of helium match those of the other Noble Gases, hydrogen does not really fit into any group. A brief summary of their properties is given below.
Hydrogen is a chemical element with chemical symbol H and atomic number 1. With a standard atomic weight of circa 7000100800000000000â 1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. Non-remnant stars are mainly composed of hydrogen in the plasma state.
