Guiding QuestionsHow do we know atoms exist?

How do we know that electrons, protons, and neutrons exist?

What is radiation and what does it come from?

Is radiation safe?

Where does matter come from?

How are elements formed?

Are all atoms of an element the same?

How do we measure atoms if they are so small?

How do we know what stars are made of?

What is wrong with this picture?
