Helium has to be classified as an element, a compound or a mixture. The mixture has to be identified as homogeneous or heterogeneous. Concept Introduction: Element: When a substance cannot be broken down into simpler substances by chemical means, it is said to be an element. Compound: When a substance can be broken down into simpler substances by chemical means, it is said to be a compound. Mixture: The combination of two or more substances which can be separated by the differences in the physical properties of the substances is said to be a mixture. Homogeneous mixture: If the composition of mixture is uniform throughout, then it is said to be homogeneous mixture. Heterogeneous mixture: If the composition of mixture is changed from one part to another, then it is said to be heterogeneous mixture.
