Study Notes
Atomic Structure
- Atoms have a central nucleus containing protons and neutrons.
- Electrons orbit the nucleus in shells.
- The nucleus is extremely small compared to the overall atom size.
- Nuclei contain protons with a positive charge (+1) and a relative mass of 1.
- Many nuclei contain neutrons, which are uncharged and have a relative mass of 1.
- The mass of electrons is negligible compared to protons and neutrons.
- Most of an atom's mass is concentrated in the nucleus.
- Protons and electrons have equal but opposite charges.
