Atomic Theory History
Who discovered that all matter around us is made of indivisible tiny particles - "atomos"
Democritus
Neutron, Proton, and Electron
The energy that is released through a nuclear reaction or radioactive process
What is atomic energy?
True or False: Nuclear power has a low carbon footprint.
True
What element is typically used for nuclear energy?
What is Uranium?
What did Michael Faraday contribute to atomic theory?
The structure of atoms is somehow related to electricity
What are the charges of the three components of an atom?
Proton (+1)
Electron (-1)
Neutron (Neutral)
The process of dividing or splitting
Fission
What are two out of three examples of nuclear energy accidents?
Three Mile Island, Chernobyl, and Fukushima
Who came up with the Plum Pudding Model?
Who is J. J. Thomson?
Who discovered that each element contains a unique number of protons (atomic #)
Henry Moseley
If Helium has an atomic number of 2 and an atomic mass of 4, how many protons, neutrons, and electrons does it have?
Protons: 2
Electrons: 2
Neutrons: 2
What happens as reactors get older?
The older reactors get, the higher the risk of accidents.
Give two pros and two cons for nuclear energy.
Answers will vary.

Protons: 5
Electrons: 5
Neutrons: 6
A chemical reaction or other process in which the products themselves promote or spread the reaction, which under certain conditions may accelerate dramatically
Who showed that radioactivity, as a spontaneous event emitting an alpha or beta particle from the nucleus, created a different element?
Who is Ernest Rutherford?
Who said that atoms are conserved in reactions?
Who said that electrons orbit the nucleus and came up with a model to show that?
Niels Bohr
Discuss the structure of an atom including the location of the proton, electron, and neutron with respect to the nucleus.
The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
What process powers the sun and and creates huge amounts of energy?
What is fusion?
How do we store nuclear waste?
The question of the storage of nuclear waste remains unresolved.
How should Christians view weapons of mass destruction?
Answers will vary.
