Ten Lightest Elements
These are the 10 lightest elements - you can also view the 10 heaviest elements, the 10 most common elements, and the Perodic Table of Elements.
The ten lightest elements starting with the lightest element, Hydrogen.
- Hydrogen - Hydrogen is the lightest and most abundant element in the universe. Hydrogen is present on earth combined with numerous other elements to form water, ammonia, carbohydrates, hydrocarbons, acids, bases, and many other substances. (Hydrogen - Symbol H - Atomic Number 1)
- Helium - Helium is the second most abundant element in the universe but scarce on earth. Helium is produced underground by radioactive decay (a emission) of other elements.
Helium is used as a flotation agent in blimps and dirigibles, a gas-displacement medium for deep-sea diving, and as a supercoolant. (Helium - Symbol He - Atomic Number 2)
- Lithium - Lithium is a reactive, silver-white metal; Helium is the lightest of all metals. (Lithium - Symbol Li - Atomic Number 3)
- Beryllium - Beryllium is a lightweight, rigid, corrosion-resistant, steel-gray metal. Used as aerospace structural material, and as moderators and reflectors in nuclear reactors. Alloyed with Cu for use in springs and electrical contacts. (Beryllium - Symbol Be - Atomic Number 4)
- Boron - Boron is a soft brown non-metal, amorphous and crystalline allotropes. Boron is used in abrasives, propellant mixtures, reactor control rods. (Boron - Symbol B - Atomic Number 5)
- Carbon - Carbon is the building block of all organic compounds. Carbon is found as four allotropes: graphite, lampblack, diamond, and buckminsterfullerene. (Carbon - Symbol C - Atomic Number 6)
- Nitrogen - Nitrogen is the most abundant element in earth's atmosphere (80%). Carbon is an essential component of ammonia, amino acids, cyanides, and many other chemicals. Carbon in liquid form serves as a refrigerant. (Nitrogen - Symbol N - Atomic Number 7)
- Oxygen - Oxygen is a very electronegative gas. Oxygen is the most abundant element on earth's surface, present in rock, water (combined with numerous other elements), and in air as O2 freed by photosynthesis in plants. (Oxygen - Symbol O - Atomic Number 8)
- Fluorine - Fluorine is a pale yellow gas. Fluorine is the most reactive halogen and the most electronegative element; Fluorine is never found free in nature, but always in compounds, such as fluorite. (Fluorine - Symbol F - Atomic Number 9)
- Neon - Neon is a colorless inert gas, glows red-orange in an electrical discharge. Trace amounts of Neon in atmosphere. Neon is used in lighting and display devices. (Neon - Symbol Ne - Atomic Number 10)
