Hydrogen (#1, H)

Metalloid Density: 101.325 kPa Melting Point: 13.99 K Boiling Point: 20.271 K Electron Configuration: 1s1 Type of Bond: covalent

Hydrogen has an Atomic Radius of 53 pm, Ionization Energy of 13.5984 ev, and an Electronegativity of 2.20 on the Pauling Scale.

Hydrogen History

Hydrogen was discovered by Henry Cavendish during an experiment with a metal acid reaction. It was discovered in England in 1766.

Hydrogen Uses and Abundance

Hydrogen is used for many things such as in the production of Methanol, and in the hydration of fats and oils. Compounds that contain this element are: water (H2O), ammonia (NH3), and hydrogen peroxide (H2O2). Hydrogen can be isolated by reacting super-heated steam with carbon or methane.

The statement above is very true. Hydrogen makes up over 90% of the atoms in the universe. It is naturally formed during chemical reactions.

Hydrogen is extremely cheap at $0.00012 per 1 mg so about $12 for every 1000 mg. Some interesting facts are that it is highly flammable, it is the lightest element, and becomes a liquid when put under extreme pressure.
