A table that compares atoms, molecules, compounds, and elements based on various characteristics:

Characteristic	Atoms	Molecules	Compounds	Elements
Basic Definition	The smallest unit of an element that maintains the properties of that element.	Two or more atoms bonded together. Can be the same or different types of atoms.	A substance made of two or more different types of atoms chemically bonded together.	A pure substance made of only one type of atom.
Composition	Composed of protons, neutrons, and electrons.	Composed of atoms bonded together in a specific ratio.	Composed of different types of atoms in a fixed ratio.	Composed of identical atoms.
Examples	Oxygen atom (O), Carbon atom (C), Hydrogen atom (H).	Oxygen molecule (O2), Water molecule (H2O), Hydrogen molecule (H2).	Water (H2O), Carbon Dioxide (CO2), Sodium Chloride (NaCl).	Gold (Au), Neon (Ne), Iron (Fe).
Properties	Has a nucleus with protons and neutrons, surrounded by electrons.	Can exhibit properties different from the atoms it is made from.	Has properties that are different from the elements it is composed of.	Has unique physical and chemical properties distinct from other elements.
Physical State	Cannot exist independently in normal conditions.	Can exist as a solid, liquid, or gas.	Can exist as a solid, liquid, or gas, depending on the compound.	Can be solid, liquid, or gas at room temperature, depending on the element.
Chemical Change	Can undergo chemical reactions, forming molecules or compounds.	Can participate in chemical reactions, breaking and forming new bonds.	Results from a chemical reaction; can also undergo further chemical changes.	Can undergo chemical reactions to form compounds.
Visual Representation	Often represented as a single circle or sphere in diagrams.	Represented as two or more circles connected, showing the bonding.	Shown as a combination of different types of atoms connected together.	Often shown as a collection of identical atoms or as a single atom symbol in the periodic table.
