Definition & Meaning
Elements, compounds, and mixtures are fundamental concepts in chemistry that describe different types of substances. An element is a pure substance that cannot be broken down into simpler substances by chemical means. It consists of only one type of atom, such as hydrogen (H), oxygen (O), or gold (Au). Elements are the building blocks of matter and are represented on the periodic table.
A compound is a substance formed when two or more different elements chemically combine in fixed proportions. For example, water (H2O) is a compound made of two hydrogen atoms and one oxygen atom. Compounds have unique properties that differ from the properties of the individual elements that compose them.
A mixture is a combination of two or more substances where each retains its individual properties. Mixtures can be homogeneous, like saltwater, where the components are evenly distributed, or heterogeneous, like a salad, where the components remain distinct. Unlike compounds, mixtures do not have a fixed composition.
