Standard Atomic Weight 1.0079 g/mol Electron Configuration 1s 1 Atomic Number 1 1 Proton 1 Neutron Oxidation States 1, -1 Under standard conditions, H exists as a diatomic gas, H 2 Most abundant element in of all elements in the universe and 3 rd most abundant element on Earth’s surface Found in molecular clouds associated with star formation and powers stars through proton-proton reaction nuclear fusion where H 2 is converted to H Hexagonal Close-Packing 3 rd layer is placed with all atoms directly above those of the first layer resulting in ABA structure. Octahedral holes are aligned exactly over each other, one set between the first 2 layers A and B, the other between the second and third layers, B and A. H 2 is extremely flammable, creating a bright yellow flame when ignited 2 H 2 + O 2 2 H 2 O (Hindenburg disaster occurred from leak of hydrogen with the air. This type of fire is normally invisible, but materials from the flying machine colored the fire. Isotopes
