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
Trace Gases. Most of our atmosphere is made up of nitrogen (78% by volume) and oxygen (21% by volume).

The most abundant of the trace gases is the noble gas argon (approximately 1% by volume). Noble gases, which also include neon, helium, krypton and xenon, are very inert and do not generally engage in any chemical transformation within the atmosphere.
