The spontaneous emission of energy from unstable atomic nuclei is called what?

Radioactivity

100
_______ is the splitting of an atomic nucleus into two smaller parts.
What is "Fission"
100

Fusion reaction is the bonding of two ____ atoms.

What is "Hydrogen"

100
The nucleus of the atom contains these two subatomic particles _____ _____.
What is "Protons and Neutrons"
100

What is a half-life?

The time it takes for half of a radioactive sample to decay

200

True or False: Radiation is harmful at any level of exposure

False: There are many beneficial aspects to radiation (X-rays, CT scans, Power plants, cancer treatment) 

200

True or False: Fission does not produce any radioactive waste

False

200

Where does fusion occur naturally?

The sun and other stars

200
These are the three types of nuclear radiation _____ _____ _____.
What is "Alpha Beta Gamma"
200

What is the relationship between half-life and the stability of a radioisotope?

The longer the half-life the more stable the radioisotope

300

What does alpha radiation consist of? (4 things)

two protons and two neutrons 

300

What is one use of nuclear fission?

Nuclear power plants (for energy), and atomic bombs, etc
300

Does fusion produce more or less energy than fission

More. Fusion produces 10 times as much energy as fission

300
Isotopes of an atom that has the same number of protons but a different number of _____
What is "Neutrons"
300

True or False: All radioactive decay curves are the same 

True, the only difference between isotopes graphs is the time it takes to decay

400

Where does natural radiation come from? (Multiple places)

Cosmic radiation (due to the explosion of stars), terrestrial radiation (from rocks and soil) and from radon gas in the Earths crust

400

What is the byproduct of nuclear fission?

Energy

400

Why is nuclear fusion difficult to produce?

It requires extremely high temperatures and pressure to occur

400
Carbon-14 has this many neutrons ____
What is "8"
400

Why must radioactive waste be properly stored and disposed over?

To not pose a danger to people or the environment
500

Name at least one use for radiation in agriculture, medicine, and scientific research? (One in each category)

Agriculture: Food Preservation, Soil and water management, pest control, crop improvement

Medicine: X-ray/CT scans/PET scans, radiation therapy, sterilization of equipment, tracers for studying body functions 

Scientific Research: Carbon dating, studying geological processes, analysing material composition, space exploration

500

What is a chain reaction in nuclear fission?

The continuation of fission after the inital fragmentation as more nuclei split causing the release of energy and smaller nuclei.

500
How is the process of nuclear fusion different than nuclear fission? Which requires heavy atomic nucleus and which requires small atomic nuclei?

Fusion is the combining of nuclei whereas fission is the splitting of nucleus.

Fusion is a process with small atomic nuclei whereas fission requires heavy atomic nuclei 

500
Different elements are distinguished by having different numbers of ________
What is "Protons"
500

What is one food that naturally produces radiation

Bananas, lima beans, carrots, and brazil nuts

This is due to the presence of the radioisotope potassium-40
