Each element is defined by the number of protons in its nucleus, which dictates its chemical identity. Methods of Separation The physical combination of substances in mixtures means that their individual properties can be exploited to separate them.

Defining Mixtures and Their Variability Unlike pure substances, mixtures contain two or more elements or compounds that are not chemically bonded. Salt dissolved in water is a classic example, where the salt is invisible but present consistently.
Understanding the classification of matter is fundamental to grasping how the world around us is constructed and how different materials interact. This variability is a key distinction; the composition of a mixture is not fixed and can be altered without changing its fundamental identity.

The Definition and Characteristics of Pure Substances A pure substance is a form of matter that has a constant composition and properties that are consistent throughout the sample. Understanding these concepts allows for the precise manipulation of materials to achieve desired outcomes.
