Facts about Carbon Chemical Element
Carbon is not the most common chemical
element in the earth 's crust. In fact, Carbon is not even
among the top ten. Carbon constitutes only 0.027% of the earth
's crust. There is more of the less familiar chemical element,

strange place, then, because carbon is the sixth most abundant
atom in the cosmos Carbon is the most abundant element we
usually regard as being a solid, but the higher concentrations
must be somewhere else in the cosmos.

Although some carbon occurs in elemental
form as graphite and diamond, most carbon is found in combined
form. Over half of carbon found occurs in
carbonate compounds such as CaCO3 .
Carbon is also found in coal, petroleum, and natural
