and can you give some examples of the kinds of compounds hydrogen forms? Thanks!

Becuase it is the lightest of all gases, occurring chiefly in combination with oxygen in water. Hydrogen combines with carbon to form an enormous variety of gaseous, liquid and solid hydrocarbons.

Like most gaseous elements, hydrogen is diatomic (its molecules contain two atoms), but it dissociates into free atoms at high temperatures. Hydrogen has a lower boiling point and melting point than any other substance except helium; hydrogen melts at -259.2° C (-434.56° F) and boils at -252.77° C (-422.99° F). At 0° C (32° F) and 1 atmosphere pressure, hydrogen is a gas with a density of 0.089 g/litre. The atomic weight of hydrogen is 1.007. Liquid hydrogen, first obtained by the British chemist Sir James Dewar in 1898 (see Cryogenics), is colourless (but light blue in thick layers) with relative density 0.070. When allowed to evaporate rapidly under reduced pressure, it freezes into a colourless solid.

Being the most common element in the universe, hydrogen has always felt it can get away with whatever it wants. It's always been a little strange because of that.

yeah water, H2O, hydrogen is different because it is the lightest of all and is the most abundant element in the universe.

it behaves differently because it very easy for it to create an octet. Also there are many things that is going to form because of this. H2O NaOH HCl HNO3 C3H6

well water for one. H2O. hydrogen peroxide, plain hydrogen, hydrogen sulfide (mixed with sulfer)

hydrogen is more of a philosophy than anything else

hydrogen has an atomic number on one, so it only has one outer electron. With only one outer electron it can only bond with atoms that have seven outer electrons

Is it because it has an atomic number of 1....? Gosh I can't remember chemistry!
