There are two types of matter. One is a pure substance, and the other is mixtures.
Pure Substances: Concept and Properties. ... The pure substance within chemistry is a very simple concept to grasp. Pure substances are defined as substances that are made of only one type of atom or only one type of molecule (a group of atoms bonded together). The measure of whether a substance is pure is known as pure substance.
An element is a substance consisting of atoms which all have the same number of protons - i.e. the same atomic number. Elements are chemically the simplest substances and hence cannot be broken down using chemical methods. Elements can only be changed into other elements using nuclear methods.
Definition of Compound. A compound is a substance formed when two or more chemical elements are chemically bonded together. Two types of chemical bonds common in compounds are covalent bonds and ionic bonds. The elements in any compound are always present in fixed ratios
Definition of Mixture. Any substance that has a uniform and unchanging composition is considered to be pure. Examples of pure substances include elements. A mixture is a combination of two or more pure substances in which each pure substance retains its individual chemical properties.
Homogeneous is Latin for "the same kind". ... Definition of Homogeneous Mixture: A mixture which has uniform composition and properties throughout. For example, air is a homogeneous mixture of gases. A teaspoonful of table salt stirred into a glass of water also makes a homogeneous mixture.
Definition of Heterogeneous Mixtures. A mixture is a combination of two or more pure substances in which the original substances retain their chemical properties. In some mixtures, the initial substances cannot be detected after they have been mixed
In chemistry, a solution is a homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent.
A suspension is a heterogeneous mixture in which solute-like particles settle out of a solvent-like phase some time after their introduction. We apply the word 'suspension' when particles are big enough to eventually settle. If the particles are too small to ever settle, they are said to form a colloid.
A colloid, in chemistry, is a mixture in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance.
