Answer 2

Two or more elements chemically combined make up a molecule or a compound

Explanation:

• A pure substance made up entirely of atoms with the same number of protons in their nuclei is known as an element. Two or more elements chemically combined make up a molecule or a compound.
• Molecule - A molecule is formed when two or more atoms come together to form an identifiable unit in which the pure material retains its chemical properties and composition even after being divided.
• For example, ozone, oxygen, dinitrogen, water, and more.
• Compound - Compounds are made up of a variety of atoms and elements that are held together by a chemical bond. There are three types of chemical bonds: covalent, ionic, and metallic.
• For example, calcium carbonate, sodium chloride, nitric acid, etc.
