100
A Helium-4 nucleus

What is an alpha particle?

100

The unit of E, in E=mc^2

What is a Joule?

100

Form of radiation capable of removing electrons from atoms

What is ionizing radiation?

100

When neutrons strike larger nuclei causing them to break into pieces

What is fission?

200

When a neutron loses this particle it becomes a proton.

What is an electron (aka a beta particle)?

200

"c" in E = mc^2

What is the speed of light?

200

A facility where the rate of nuclear decay is controlled to generate electricity

What is a nuclear reactor?

200

The combination of two or more lighter nuclei to form a heavier nucleus, releasing energy

What is nuclear fusion?

300

The most penetrating, but least ionising form of nuclear decay

What is gamma radiation?

300

An alternate mass unit for kg at the atomic level, with an acronym of AMU.

What is the atomic mass unit?

300

Atoms of the same element containing varying amount of neutrons

What are isotopes?

300

This is one benefit of nuclear fission

What is an energy source that doesn't release carbon?

400

Binding energy comes from an apparent loss in mass of the constituent nucleons, and is known as this term

What is mass defect?

400

This amount of energy is released from a mass defect of 1 kg, if c = 3 x 10^8 m/s

What is 9 x 10^16 J?

400

Energy needed to remove a particle from a given nucleus

What is binding energy?

400

This is one benefit of nuclear fusion over nuclear fission

What is almost no risk of nuclear meltdown/runaway reactions, or limited nuclear waste?

500

This subatomic particle is not part of the binding energy equation due to its location in the atom.

What is an electron?

500

This is the amount of mass that was converted into 9.00 x 10^16 J of energy by a nuclear process. Use m = E/(c^2)

What is 1 kg?

500

A runaway, uncontrolled nuclear fission reaction can be done on purpose to build this

What is an atomic/nuclear bomb?

500

This is one challenge to making nuclear fusion a viable energy source

What is materials that can handle plasma for long enough and hot enough, or finding enough tritium as a fuel source?
