A mineral
Matter with only one particular kind of atom is known as an element. These atoms can either be located individually or combined into larger units. An example of this would be the notion that carbon is an element, because at it's pure substance state it's composed of only carbon atoms.
Homogeneous matter
Matter also may composed of one element only as Coal, Graphite and Diamond are only Carbon.
Elements are matter made of one kind of atom.elements
there is only one kind of matter in a pure sustance
A pure substance is either an element or compound. Elements are composed of only one kind of atom, and compounds are composed of a definite proportion of atoms of different elements that is always the same.
Elemental matter.
An element is composed of only one kind of atom. A compound is composed of atoms of more than one element.
Material made up of only one kind of matter is called an Element
All matter, such as solids, liquids and gases, is composed of atoms. Any material that is composed of only one type of atom is called a chemical element.
