The Elements: Hydrogen
Created | Updated Apr 16, 2007
Welcome this is the first page of the elements database. We will obviously start with the first element, Hydrogen.
Hydrogen's chemical formula is H but it is commonly found in the molecular state and therefore it is usually H2. Hydrogen is the lightest element, with a Relative Atomic Mass of 1. This means that it is incredibly floaty, this would be rather strange if it was a solid. But it isn't. Hydrogen's state of matter is gaseous at room temperature and pressure* and in any case, it is colourless.
The uses of Hydrogen in the past have been for gases in Air ships (until that huge explosion, now they use Helium, more on that next week), the element has also bee used to create water from its molecular counterparts Hydrogen and Oxygen. There haven't been many other uses because it is a fairly useless material.
The most recent uses of Hydrogen have been rocket fuel, due to its high reactivity Hydrogen is mixed with oxygen and nitrogen and ignited to provide vast amounts of energy for lift off.
Hydrogen's natural form is in the oxide, Hydroxide, which is commonly known as water. Water is an abundant compound that is liquid at room temperature and pressure. This liquid is what makes up just over 70% of us apes. Hydrogen also makes it's appearance in many other life-giving compunds, for instance, glucose, the long-chain hydrocarbon with the formula C6-H12-06. Glucose as you may know is the base energy and greatest source of Adrenosine Triphosphate - more commonly known as ATP - for plants.
That's it for this week, stay tuned for more element related fun next week!!! (or earlier if I can be bothered)
*Room tempreature is considered as being 37 degrees centigrade and room pressure is considered to be 1 Atmos.
