Facts about Hydrogen:
- Hydrogen: Colourless, odourless, highly explosive gas at standard conditions, and burns with a nearly invisible flame.
- Fun fact about Hydrogen: Hydrogen is the lightest element in the periodic table, having only one electron and one proton. Yet, this tiny element can pack a big punch in the way of fuels for everything from cars to rockets!
- Chemical symbol: H
- Atomic number: 1
A crystal structure containing Hydrogen:

Facts about this structure:
- Formula: C21H21NO3
- Structure name:1-(7,9-diacetyl-11-methyl-6H-azepino[1,2-a]indol-6-yl)propan-2-one
- Fun fact about the structure: Most every structure in the CSD includes Hydrogen. This one in particular is the millionth structure added to the CSD, and it was part of a study of organic catalysts.
- CSD refcode: XOPCAJ (What’s this?)

Hydrogen is ubiquitous in the atomosphere, in the earth and in all living things. It readily forms compounds with other elements such as oxygen (water), carbon (methane), nitrogen (ammonia) and many others. Because elemental hydrogen is very reactive, specifically with oxygen, it is often used in rocket engines which require a tremendous amount of thrust. Hydrogen is a clean source of energy and doesn’t contribute to pollution or greenhouse gases. This is why many scientists and automobile manufacturers are looking for ways to build safe, reliable vehicles which use hydrogen instead of petrol as fuel.
