Hydrogen Facts | Facts about Hydrogens

What are the most abundant chemicals in the universe and earth?

Hydrogen is the most abundant chemical in the universe and oxygen is the most abundant chemical element in the earths crust, water and atmosphere.

Hydrogen is the most abundant element in the universe, making up about 75% of all normal matter by mass.

Hydrogen is the lightest element, with an atomic number of 1. Its most common form is just one proton and one electron.

Hydrogen was named by French chemist Antoine Lavoisier, and its name means "water-former" because burning it produces water.

English scientist Henry Cavendish identified hydrogen as a distinct element in 1766, calling it "inflammable air."

The Hindenburg airship was filled with flammable hydrogen gas, which is why it was destroyed so quickly by fire in 1937.

The Sun fuses about 600 million tons of hydrogen into helium every second.

Hydrogen fuel cell vehicles combine hydrogen with oxygen to make electricity, and their only tailpipe emission is water.

Scientists think the intense pressure inside Jupiter squeezes hydrogen into a liquid metal that can conduct electricity.

Hydrogen has three isotopes: protium, deuterium, and tritium. Radioactive tritium is used in some self-glowing exit signs.

Hydrogen bonds between water molecules give water many of its unusual properties, like its high boiling point and the way ice floats.

Uranus's clouds contain hydrogen sulfide, which would make them smell like rotten eggs.
