no both iron and silicon are elements. chemical compounds aretwo or more elements.
Sand on the beach is a mixture of compounds. Pure sand is white and its chemical name is Silicon Dioxide (SiO2)' a compound. The red brown colour comes from iron(III) salts mixed in ther sand. The Iron(III) saltsd will also be a mixture of compounds.
silicon and carbon
Silicon is an element, and therefore by definition no compounds are found in it!
Basic chemical elements in Portland Cement are calcium, silicon, aluminum and iron oxide.....
Iron is an element, not a compound; a wide variety of compounds can be formed from Iron (Fe)
iron, nitrogen, sulfur, oxygen, silicon
One silicon atom = Si Two oxygen atoms = O2 Chemical formula for silicon dioxide compound = SiO2
Silicon can be combined with many elements forming chemical compounds as fluorides, chlorides, carbides, nitrides, etc.
Iron sulphides are chemical compounds.

Iron sulfide and many other compounds are available from chemical supply companies.
Magnets can be made out of nickel, iron, cobalt, intermetallic compounds and chemical compounds.
Amphiboles are minerals containing mostly silicon, oxygen, iron, and magnesium.

These compounds are iron oxides.
