WebThe earth is full of a wide variety of rocks and minerals which provides the soil to grow vegetation and support life. The two most common elements in the earth’s crust are oxygen (46%) and silicon (28%). Because of this, the most abundant mineral in the earth’s crust is silica (silicon dioxide). WebThe elements silicon, germanium, tin and lead are also in group 14. Carbon has some similarities to the metalloid silicon, but silicon cannot be the basis for life like carbon can. It is sometimes called the “king” of the periodic table. Carbon is a non-metal, found in nature as graphite, diamond or fullerenes.
