Study Notes
Atomic Structure
- Atoms are the fundamental building blocks of matter.
- Atoms are composed of four basic parts: protons, neutrons, electrons, and a nucleus.
- The nucleus contains protons and neutrons.
- Protons are positively charged.
- Neutrons have no charge.
- Electrons are negatively charged and orbit the nucleus.
- The number of protons in an atom determines its element.
Atomic Properties
- The number of electrons determines an atom's chemical properties, including its melting and boiling points.
Quantum Mechanics
- Quantum mechanics explores the behavior of atoms and the particles that make up atoms.
Periodic Table
- The periodic table organizes all known elements.
Additional Information
- The word "atom" comes from the ancient Greek word "atomos," meaning "uncuttable" or "indivisible."
- Powerful microscopes allow scientists to visualize individual atoms.
- The strong force holds the nucleus together.
