    Both elements and compounds are types of substances. But, there distinct differences are as follows:-

    1) Composition

    – Elements are pure substances made up of only one type of atom. Atoms of the same element have same number of protons. Examples- hydrogen, oxygen, carbon etc.

    -A compound is composed of two or more different elements chemically combined together in a fixed ratio. Examples- Water(H2O), carbon dioxide(CO2) etc.

    2) Chemical properties

    -Elements have same chemical properties which are determined by the number and electrons in their atoms.

    – As compounds are mixture of elements chemically bounded together, they exhibits different chemical properties from the elements they are formed.

    3) Physical properties

    -Elements have unique set of physical properties such as boiling point, melting point, color, density etc which vary depending on the arrangement and interactions of atoms

    -Compounds possess physical properties that may be distinct from the properties of their constituent elements.

    4) Separation

    – Elements cannot be broken down into simpler substances by ordinary chemical means.

    -Compounds can be broken down into their constituent elements or simpler compounds by chemical reactions

    These can be the differences between compounds and elements.
