A compound contains two or more elements chemically joined together.
Are elements and compounds two types of substances. Compounds are defined as substances composed of two or more different elements that are chemically combined. Compounds always contain atoms of their constituent elements in the same numerical ratio regardless of how the compound was prepared. Compounds have physical and chemical properties that help us identify them.
Oxygen is an element because it is made up of only one type of atom. An element contains atoms with the same atomic number. Butane and benzene are both compounds.
Two different types of atom ie. An element is always represented by a symbol consisting of two letters such as He. A heterogeneous mixture is a mixture of two or more chemical substances elements or compounds where the different components can be visually distinguished and easily separated by physical means.
Compounds consist of two or more different types of atom. This mineral deposit is composed of a mixture of substances. They contain multiple elements bonded together in a specific ratio.
Substances exist as elements compounds or mixtures. A compound can easily be split up into its different elements. Kerosene and gasoline are mixtures because they are combinations of several compounds.
Consequently analysis of any pure compound always returns the same result.
