4. Atomic Radius Analogy KEY: Justin Bieber is the nucleus. The people are the electrons. In the first level, the mosh pit is full of people who are trying to get closer to Justin Bieber so they are packed together very tight and small.
5. Atomic radius Analogy As you get to the farther away from Justin levels the people (electrons) spread out because there is more room and the pull from Justin is not that strong.
6. Ionization Energy Analogy Key: The Stadium is the nucleus The cars are electrons. In the first level, all the parking spots next to the stadium are filled and those cars (electrons) are packed together so it would take a lot of energy to move or leave. In the second level, the cars are more spread out so it allows them to leave easily with less energy then the first level.
