no both iron and silicon are elements. chemical compounds aretwo or more elements.
Silicon is a element.! this is because anything from the periodic table is in fact elements! :)
A marble is not an element. It is a mixture of a variety of compounds which are in turn made up of several elements. The identities of those elements and compounds depends on the marble. Common elements include silicon, oxygen, and boron.
Nickel and silicon are elements. Gasoline is a homogeneous mixture.
Wood is a MIXTURE of many compounds, so your answer would be a mixture.
No. Elements, compounds and mixtures are 3 different terms.
Silicon can be combined with many elements forming chemical compounds as fluorides, chlorides, carbides, nitrides, etc.
Smoke is a heterogeneous mixture.
Silicon is the element. Others are compounds of different elements.
No, silicon (Si) is not a covalent compound itself; it is an element. However, silicon can form covalent compounds when it bonds with other elements. Silicon is commonly found in covalent compounds such as silicon dioxide (SiO2) and silicon tetrafluoride (SiF4).
Yes, a mixture may consist of elements and compounds. A mixture is formed when two or more substances are physically combined without forming a new substance, so it can contain elements and compounds in various proportions.
Reactants can be a mixture, compounds, a mixture of compounds and also elements. It depends on the reaction. Air is a mixture and is often a reactant for example.
