Unit 2: Atomic structure and Nuclear reactions
Part 1: Big Idea: The atom is the basic unit of chemistry and is composed of protons, neutrons and electrons.
Part 2: Big Idea: Electrons are arranged in a specific geometric areas around the nucleus and moving from one area to another involves a specific amount of energy.
