Re-jigger the arrangement, and â presto! â the atoms form diamond, one of the hardest materials in the world. Carbon is also the key ingredient for most life on Earth; the pigment that made the first tattoos; and the basis for technological marvels such as graphene, which is a material stronger than steel and more
Oxygen occurs uncombined (as one of a mixture of gases) in air, but it also readily combines (reacts) with a wide variety of other elements to make compounds. Indeed, oxygen is among the most reactive of all the elements. For example, nearly allthe rocks of the Earth are compounds containing oxygen.xygen in water. In the past, oxygen atoms combined with hydrogen atoms to form water. Oxygen is a much more massive element than hydrogen (the atomic weight of hydrogen is 1, that of oxygen is 16). As a result, oxygen makes up about nine-tenths of the mass of the oceans.
