Silver: Element (made up of only one type of atom)ĥ.Ĝalcium carbonate: Compound (made up of atoms of the elements of calcium, carbon and oxygen, held together by chemical bonding)Ħ. Sugar Solution: Mixture (because sugar can be easily separated from water by crystallisation)Ĥ. Soil: Mixture (composed of small pieces of a variety of material, so it is a heterogeneous mixture)ģ. Sodium: Element (made up of only one type of atom)Ģ. Therefore let us classify the options on the basis of the above mentioned definitions.ġ. A mixture is a physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspensions and colloids. Mixture: In chemistry, a mixture is a material made up of two or more different substances which are physically combined. Two atoms of the same element bonded in a molecule do not form a chemical compound, since this would require two different elements. In case the number of protons in the atom gets changed then the type of the element is changed.Ī chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds.
Discuss about each one of them individually to get a better idea.Īn element is a substance that is made entirely from one type of atom. So, we need to know the basic unit structure before, in order to classify the mentioned options.
Hint: Classification between elements, compounds and mixtures are made on the basis of their compositions.
