1. Hydrogen Name: Hydrogen Atomic number: 1 Atomic Weight: 1.00794 grams/mole Standard state: gas at 198 K Hydrogen is the lightest Hydrogen is the lightest element. It is by far the most abundant element in the universe and makes up above 90% of Universe by weight. Hydrogen as water (H2O) is absolutely essential to life and it is present in all organic compounds. Hydrogen is lightest gas. Hydrogen gas was used in lighter-than-air balloons for transport but is far too dangerous because
