Half-lives

Sub-Atomic Awesomeness100

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

• Answer: Protons & Neutrons

Sub-Atomic Awesomeness200

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

• Answer: Protons & Neutrons

Sub-Atomic Awesomeness300

• How are neutrons formed?

• Answer: Protons & electrons fuse together.

Sub-Atomic Awesomeness400

• What is an isotope?

• Answer: An element with a different number of neutrons

Sub-Atomic Awesomeness500

• What’s the difference between carbon-12 and carbon-14?

• Answer: Carbon-14 has two more neutrons

Sub-Atomic Awesomeness600

• What sub-atomic particle is referred to as “nuclear glue?” Why?

• Answer: Neutrons because they hold protons together in the nucleus.

What the Heck?100

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

• Answer: Silicon

What the Heck? 200

1. 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.

What the Heck? 300

• What the heck is a nuclear reaction?

• Answer: It is a reaction that takes place in the nucleus.

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.

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

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

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.

Q & A 200

1. How is the atomic mass or weight calculated?

• Answer: Adding the protons and neutrons together.

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.

Q & A 400

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

• Answer: MostDense

Least Dense

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

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.

Reaction Jackson 100

1. Beta decay involves the decay of what sub-atomic particle from this particle in the nucleus?

• Answer: electrons from neutrons

Reaction Jackson 200

• Alpha decay or alpha emission is the loss of what particular ion?

• Answer: Helium

Reaction Jackson 300

• What is a fission reaction?

• Answer: Forces pulling the nuclei of an atom apart.
