Elements are pure substances made up of atoms
The answer is compound hope this helps.
Atoms
Explanation:
Atoms are the smallest particle that can be identified from a chemical element and participate in chemical reactions.
All atoms are composed (at least) of a proton and an electron, and may also have neutrons (the hydrogen atom has no neutron).
Elements are substances composed of atoms of a certain type.
A molecule is formed when atoms of the same or different elements combine. A molecule is the smallest particle of a substance that can normally exist independently.
Example: A carbon atom combines with two oxygen atoms to form a carbon dioxide molecule [CO₂]
A compound is formed when atoms or molecules of different elements combine. In a compound, the elements are chemically combined in a fixed ratio.
Example: Hydrogen and oxygen are combined at a fixed ratio of 2: 1 to form the water compound [H₂O].
Elements are pure substances comprises atoms.
Explanation:An element is a substance that can't be separated into some other substance. Each element is comprised of its own kind of atom. This is the reason the chemical elements are for the most part mere different from one another.
The periodic table records all the discovered elements, gathering those with the same properties. The elements includes metals, non-metals, and metalloids. Most elements are metals, which conduct electricity and are shiny in nature. Metals incorporate iron, gold, and aluminum which are solid at room temperature.

Elements are pure substances made up of what?
atoms
Explanation:
An atom is smallest unit of a matter or substance.It consist of three subatomic particles : electrons, protons, neutrons. It may or may not have independent existence.
A molecule of element is formed by combination of atoms of similar elements. [tex]H_2[/tex]
A molecule of compound is formed by combination of atoms from different elements.Example: [tex]CuCO_3[/tex]
Element is a pure substance which is composed of atoms of similar elements. Example: [tex]Cu[/tex]
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. Example: [tex]CuO[/tex]
