Elements, Compounds, and Mixtures

Differences between Elements, Mixtures, and Compounds:

Elements: Elements are pure substances made up of only one type of atom. They cannot be broken down into simpler substances by chemical means. Each element is represented by a unique chemical symbol and atomic number on the periodic table.

Mixtures: Mixtures are composed of two or more substances that are physically combined and can be separated by physical means. The components of a mixture retain their individual properties and can be present in varying proportions. Mixtures can be homogeneous (uniform composition throughout) or heterogeneous (non-uniform composition).

Compounds: Compounds are substances formed when two or more elements chemically combine in fixed ratios. The components of a compound are chemically bonded and cannot be separated by physical means but require chemical reactions. Compounds have distinct properties different from the elements they are composed of
