| If and element conducts electricity, does it react with hydrochloric acid?3 | No3
| How does a cathode ray react with the negative side of a magnet?4 | It repels.4
| Why was Rutherford surprised when some of the alpha particles bounced back off the gold sheet?5 | Because it meant that the particles were positively charged.5
| What are the wavelengths of the electromagnetic spectrum?(no specific order)6 | Ultraviolet, infrared, X-rays, gamma rays, micro waves, radio waves, and visible light.6
| What was the name of Bohr's atom model?7 | Planetary Model7
| What happens in the photoelectric effect?8 | A photon and an electron on the surface of a metal collide.8
| What is the Heisenberg uncertainty theorem?9 | It states that it is impossible to determine the exact position and momentum of an electron at the same time.9

| Where are the s,p,and d blocks located?13 | Point it out on the table13
| What is the octet rule?14 | Atoms tend to gain or lose electrons during chemical reactions, so that they the atoms have an outer shell configuration of 8 electrons14
| What is an isotope, and what makes an isotope what it is?15 | Isotopes are atoms of the same element that have different masses due to the different number of neutrons.15
| What's the difference between fusion and fission?16 | In fusion atoms combine to from a larger nucleus. In fission, you bombard an atom with a neutron and it breaks into different elements.16
