2. The Big and The Small The Power of Ten
Q1. If the Sun was the size of an orange, what and where should be Earth to represent correctly our Solar system to scale?
Sun size: 109x Earth
Earth-Sun Distance: 215 x Sun Radius

3. Atoms vs. the Solar System

4. The Big and The Small
Q2. If the nucleus was the size of an orange, where should be the next nucleus of two adjacent Hydrogen atoms?
Atomic size: 316 x Nucleus
Mass of nucleus: approx x electron

5. Pictures from the Microscopic World
Scanning Tunneling Microscope (1986 Physics Nobel)
Atomic Force Microscope

6. Inside the Atom Nucleus: Protons and Neutrons
Electrons around the Nucleus
Number of protons = Number of Electrons
Protons and Neutrons add up to almost all the mass of the atom
Element determined by number of protons/electrons
