How does an atom differ from a molecule? In what ways are they similar?

Atom

• An atom is defined as the smallest particle within the element which cannot bedivided or broken to form any other substances by any chemical reaction.
• It is the smallest entity within the element.
• It has three types of subatomic particles calledprotons, neutrons, and electrons.

Molecule

• A molecule is defined as the smallest particle with a compound that can be divided to form atoms, compounds, or any other substances by any chemical reaction.
• It is the smallest entity within thecompound.
• The atoms are linked to produce a molecule.

• The atoms are linked to form molecules while molecules connect to form larger molecules.
• They are the smallest constituent particles.
• All atoms or molecules are connected by chemical bonds.

Ex., O, Mg and H are the atoms of Oxygen, Magnesium, and Hydrogen elements respectively and CsF and NaOH are the molecules ofcesium fluoride and sodium hydroxide respectively.
