A pure substance made of only one kind of atom is called an element. Elements are the simplest form of matter and cannot be broken down into simpler substances by chemical means. Each element is represented by a unique chemical symbol, such as "H" for hydrogen or "O" for oxygen, based on its atomic structure. Examples of elements include hydrogen, oxygen, carbon, and gold.
A substance that only contains one kind of atom is called an element.
An Element is the substance consisting of only one type of atom
A substance that is made up of only one atom is called a pure substance. A pure substance is also called an element on the Periodic Table.
Elements are made up of only one kind of atoms. For example graphite and diamond are forms of the element carbon, and only contain carbon atoms.Atoms of a single element may combine as molecules, or structurally as allotropes, in a number of ways.
