No. Sand is a mixture of different substances. The term metalloid applies to a particular class of elements. One metalloid, silicon, is one of the most abundant elements in sand to the point that silicon is often extracted from sand.
Sand is silicon dioxide, formula SiO2
Sand and water mixed is a mixture. Elements are substances with only one type of atoms. Compounds are substances made up of chemically bonded particles. Since sand and water are neither of these, it must be a mixture.
the chemical formula for sand is SiO2, so it is a compound, made from Silicon and Oxygen
A compound substance is one that is made up of two or more elements.
It's a compound. H2O - Two hydrogen atoms, one oxygen atom Water is a compound as it can be reduced to simpler elements (Oxygen and water).It is a homogenous mixture("the same") as it is uniform throughout. E.g: Salt and sand mixed together would be a heterogenous mixture("different") as you can distinguish between sand and salt. A pure 'mixture' is usually homogenous, especially liquids.
Sand is a mixture and rarely is only one compound.
Yes, a chemical compound is composed of two or more elements that are chemically bonded together in fixed proportions. The elements in a compound are held together by chemical bonds, such as ionic or covalent bonds.
A 'compound' is composed of several 'elements'. Don't confuse them with the 'atom'/'molecule' distinction - e.g. H20 is a compound because it has H and O, but Hydrogen in its natural state comes as H2 (2 H atoms), but still only ONE element (H).
Carbon monoxide is a compound molecule. It is a compound because it is the combination of two elements viz., carbon(C) and oxygen(O), to form the molecule carbon monoxide (CO). A molecule is species that exists on its own , and can be a combination of two different atoms or two atoms the same.
A binary compound is one that is composed of two elements.
Two or more elements make up a compound, and oxygen has one.
