Atom and Molecule Quiz

Atomic Structure

• Protons and neutrons are found in the nucleus of an atom, which is the central part of the atom.

Atoms and Molecules

• An atom is the smallest unit of a chemical element, consisting of a nucleus and electrons.
• A molecule is a group of two or more atoms that are chemically bonded together.
• The key difference between an atom and a molecule is that an atom is a single unit, while a molecule is a group of atoms bonded together.
• Atoms can exist independently, but molecules are formed when atoms share one or more pairs of electrons to form a chemical bond.
