Study Notes
Atoms and Molecules
- Atoms are the basic units of matter, comprising protons, neutrons, and electrons.
- Protons have a positive charge (+1), neutrons are neutral (0), and electrons carry a negative charge (-1).
- Protons and neutrons reside in the nucleus, while electrons are found in orbitals surrounding the nucleus.
- The atomic number of an element is determined by the number of protons it contains.
- Mass is primarily concentrated in the nucleus, with protons and neutrons contributing to nearly all atomic mass.
- The arrangement of electrons governs chemical properties and reactions of an atom.
- Molecules are formed when two or more atoms bond together, creating different substances with distinct properties.
- Chemical bonds include ionic bonds (formed through electron transfer) and covalent bonds (formed by sharing electrons).
- Understanding atoms and molecules is fundamental to studying chemistry, as they explain how matter interacts and transforms.
