Hydrogen is a gas.

Even though Hydrogen hangs out around the metals,

rachelcbalon — 2013-11-07 17:14:14 UTC

It is actually nonmetal

Hydrogen is a Group 1 Element

rachelcbalon — 2013-11-08 16:42:32 UTC

Group 1 is the alkali metals. Though hydrogen is placed here, it is only part of group 1; it is not considered an alkali metal.

Discovery

rachelcbalon — 2013-11-08 17:00:00 UTC

Henry Cavendish discovered hydrogen in 1766

FUN FACT

rachelcbalon — 2013-11-08 17:05:57 UTC

In its most basic and most abundant form, hydrogen is composed of only one proton and one electron. This makes it the lightest element. In fact, it is so light that single atoms of it can float right out of Earth's atmosphere!

Hydrogen is...

rachelcbalon — 2013-11-08 17:11:19 UTC

A colorless, odorless gas
The most abundant element in the universe
On earth, lone hydrogen is found mostly in volcanic gases.

Critical Numbers

rachelcbalon — 2013-11-09 17:54:27 UTC

Boiling Point : -252.762°C

Melting Point : -259.2°C

Naming

rachelcbalon — 2013-11-09 19:40:32 UTC

"Hydrogen" comes from the Greek words "hydro" and "genes" meaning "water" and "generator".

Uses

rachelcbalon — 2013-11-09 19:47:06 UTC

Liquid hydrogen is important in cryogenics and the study of superconductivity because its melting point is just above absolute zero.

Commonness

rachelcbalon — 2013-11-09 20:58:46 UTC

On earth, hydrogen is found mostly in water molecules.

The Diatomic Seven

rachelcbalon — 2013-11-09 21:21:04 UTC

Even though it is nowhere near the others on the periodic table, hydrogen is a part of the diatomic seven. This is a group of elements that never appear as only one atom. They are always attatched to something, be it another element(s) or another atom of itself.
