Elements, Mixtures and Compounds are the names of types of chemicals. Chemistry describes the structure and behaviours of different types of substances and in order to do so chemists classify different types of materials according to the particles that form them and how those particles are arranged.

Still, most of these elements are found in mixtures. When two distinct elements are chemically combined—, chemical bonds form between their atoms—the result is called a chemical compound. Most elements on Earth bond with other elements to form chemical compounds, such as sodium (Na) and Chloride (Cl), which combine to form table salt

Mixtures Vs. Compounds. The law of constant composition states that the ratio by mass of the elements in a chemical compound is always the same, regardless of the source of the compound. The law of constant composition can be used to distinguish between compounds and mixtures of elements: Compounds have a constant composition; mixtures do is always % O and % H
