Big Ideas
- Atoms and ions are made up of protons, neutrons, and electrons, each with distinct masses, charges, and locations.
- Understanding the structure and organization of subatomic particles is fundamental to explaining the properties and behaviors of atoms and ions.
Essential Questions
- What are the masses, charges, and locations of protons, neutrons, and electrons?
- How does the arrangement of subatomic particles define the structure of atoms and ions?
- How do differences in particle number and arrangement distinguish atoms from ions?
- Why is it important to know where protons, neutrons, and electrons are located within atoms and ions?
- How does the presence or absence of certain subatomic particles affect the properties of an atom or ion?
