A nonmetallic chemical element in the carbon family of elements. Silicon-atomic symbol Si - is the second most abundant element in the earth's crust, surpassed only by oxygen.Silicon does not occur uncombined in nature. Sand and almost all rocks contain silicon combined with oxygen, forming silica.When silicon combines with other elements, such as iron, aluminum or potassium, a silicate is formed. Compounds of silicon also occur in the atmosphere, natural waters, many plants and in the bodies of some animals.and and almost all rocks contain silicon combined with oxygen, forming silica.
