Study Notes
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.
