What makes hydrogen so special?

Answer 1

There is a lot of it and when it reacts with oxygen the only thing produced is heat and water.

Answer 2

Many things. I'll list the first few that come to my mind:

1. Its most common isotope has only one proton, and one electron.
2. It is one of only seven elements which exist almost exclusively as diatomic molecules at STP.
3. You can measure the pH of a solution by measuring the concentration of H^+^ (please note that the carrots surrounding the + indicate that it should be superscript) ions in a solution (which are essentially protons).
4. Because it is a very simple element, its behavior in the gaseous state is very similar to that of an ideal gas. Ideal gases are awesome.
5. Hydrogen is responsible for a special type of intermolecular and intramolecular attraction known as hydrogen bonding. Hydrogen bonding is responsible for the high boiling point of water, and more complicated structures of proteins. If either of these things did not exist you would not be alive.
6. When you burn hydrogen, it causes the following reaction to occur (a number surrounded by underscores indicates a subscript):

2H_2_ + O_2_ -> 2H_2_O

That's right, it produces water. Which is awesome. On top of that, if you fill a balloon with hydrogen and touch a heat source to the balloon, not only will that reaction occur, but it'll blow up in a really awesome way.

7. When you throw sodium into water, it produces a lot of hydrogen gas. The heat of the reaction is so great that the hydrogen gas ignites immediately and blows up in an extremely cool fashion. If you have not seen this in person by throwing large amounts of sodium into a river as I have, I recommend you do so (just don't get caught by the cops!).

If I think of anything else, I'll add it here later.

EDIT:

8. It makes up more than 90% of all atoms, or three quarters of the mass of the universe. That means it's the most abundant element in the universe.

Answer 3

It's all like "Woah, I'm hydrogen." Special enough, I say.

Actually because it's the closest thing we've got to an Ideal Gas, where each individual atom is assumed to have no volume (real gases do, hydrogen having the least) and their Intermolecular Forces do not attract at low temperatures or high pressures (real gases form solids and liquids at these points, hydrogen takes very low temperatures and very high pressures to do this).

Answer 4

Dopefish has been sucking on hydrogen it seems.

Answer 5

It is explosive as well is found in water that covers 80% of the planet.

Answer 6

because it's a key element in water (H20!!!)
