Sub-Atomic Awesomeness100

• What particles make up most of the mass of an
  atom?
• Answer Protons Neutrons

4
Sub-Atomic Awesomeness200

• What particles can be found in the nucleus of an
  atom?
• Answer Protons Neutrons

5
Sub-Atomic Awesomeness300

• How are neutrons formed?
• Answer Protons electrons fuse together.

6
Sub-Atomic Awesomeness400

• What is an isotope?
• Answer An element with a different number of
  neutrons

7
Sub-Atomic Awesomeness500

• Whats the difference between carbon-12 and
  carbon-14?
• Answer Carbon-14 has two more neutrons

8
Sub-Atomic Awesomeness600

• What sub-atomic particle is referred to as
  nuclear glue? Why?
• Answer Neutrons because they hold protons
  together in the nucleus.

9
What the Heck?100

• What the heck is made when carbon and oxygen fuse
  together?
• Answer Silicon

10
What the Heck? 200

• What the heck happens to the amount of energy
  produced when the size of particles decrease?
• Answer As the size of particles decrease, the
  amount of energy produced increases.

11
What the Heck? 300

• What the heck is a nuclear reaction?
• Answer It is a reaction that takes place in the
  nucleus.

12
What the Heck? 400

• What the heck is the difference between fusion
  and fission?
• Answer Fusion is when forces PUSH nuclei
  together. Fission is when forces PULL nuclei
  apart.

13
What the Heck? 500

• What the heck are the answers to these three
  fusion reactions?
• H ? He
• Ne He ? ?
• C O ? ?
• Answer
• 4H ? He
• Mg
• Si

14
What the Heck? 600

• What the heck are answers to these two fission
  reactions?
• U-236 undergoes fission producing Sr-90, 3
  neutrons, and what other product?
• U-236 undergoes fission producing Ba-142, 3
  neutrons, and what other product?
• Answer
• Xe-143
• Kr-91

15
Q A 100

• Why does temperature in the center of stars have
  to be extremely high for fusion to occur?
• Answer So atoms can move fast enough to
  overpower repelling forces in the nucleus.

16
Q A 200

• How is the atomic mass or weight calculated?
• Answer Adding the protons and neutrons together.

17
Q A 300

• If you had 20 grams of sodium chloride, which
  isotope would contribute more atoms, chlorine-35
  or chlorine-37? Explain your reasoning.
• Answer Cl-35 because is has a lower mass.

18
Q A 400

• Where would the most dense gases be found inside
  a star? Explain using a labeled diagram.
• Answer

Most Dense
Least Dense
19
Q A 500

• Thorium-234 has a half-life of 24 days. How many
  grams of thorium-234 would remain from 100g after
  72 days?
• Answer 12.5 grams

20
Q A 600

• Are nuclear reactions in stars due to chain
  reactions? Explain your reasoning.
• Answer No, nuclear reactions in stars are due to
  fusion reactions. Chain reactions only occur
  during fission reactions.

21
