The Architecture of Matter · Atomic Structure
Subatomic Particles and Isotopes
Investigation into the discovery of protons, neutrons, and electrons and how their arrangement defines atomic mass and stability.
Key Questions
- 1What evidence do we have for the existence of subatomic particles we cannot see?
- 2How does the ratio of neutrons to protons influence the stability of a nucleus?
- 3Why do different isotopes of the same element behave identically in chemical reactions?
