Elements and compounds are pure chemical substances found in nature. The difference between an element and a compound is that an element is a substance made of same type of atoms, whereas a compound is made of different elements in definite proportions.Examples of elements include iron, copper, hydrogen and oxygen.eaning. A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. Distinguishing Feature. Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds.
Note that a compound: 1  consists of atoms of two or more different elements bound together, 2  can be broken down into a simpler type of matter (elements) by chemical means (but not by physical means), 3  has properties that are different from its component elements, and.4  always contains the same ratio of its component atoms. molecule consists of two or more atoms of the same element, or different elements, that are chemically bound together. Note that the two nitrogen atoms which comprise a nitrogen molecule move as a unit.
