Nuclear Physics H

Nuclear Forces

100

This is what holds the nucleus of an atom together.

What is the Strong Nuclear Force?

200

This force is what causes atoms to decay.

What is Weak Nuclear Force?

300

When Strong Nuclear Force is utilized to generate energy, it is through this process.

What is Nuclear Fission?

400

This is the process by which massive amounts of nuclear energy is generated by taking advantage of the Strong Nuclear Force.

What is Nuclear Fusion?

500

This is what the decay of large or unstable elements is called, and is a principal part of Nuclear Physics.

What is Radioactivity?

Radioactivity

100

Radiation of particles, as well as decay of elements happens to these types of elements.

What are larger, unstable elements? (i.e. U-235)

200

This particle is a product of nuclear decay, and denotes a loss of two protons.

What is an Alpha Particle?

300

This type of decay is the least penetrable type of radiation, and is a result of an atomic nucleus gaining a proton.

What is a Beta Particle?

400

This particle is of the highest energy, and will penetrate most surfaces- it is a result of electrons within the atom changing energy levels.

What is a Gamma Particle?

500

Before a radioactive element decays it is known as a _________ and after it is called a ____________

What are parent isotope and daughter isotope?

Half Life

100

In a single half- life, and element decays by this much.

What is half of an element?

200

We started with 400 grams of element J, and after 1 hour, we had 100 grams of element J left. Its half life is

What is 30 minutes?

300

Shorter half lives mean that a given element or elemental isotope is less of this, while longer half lives are stronger indicators of this characteristic.

What is a stable element?

400

An element that has a high amount of this usually has a very short half life, and should be regarded very carefully when handling.

What is radioactivity?

500

A 100 kg sample has a half-life of 25 mins. After 75 mins how much of the sample is left?

What is 12.5 kg of sample

Miscellaneous

100

This particle is the opposite particle of an electron.

What is a positron?

200

This particle sits outside of the nucleus of an atom

What is an electron?

300

When an Alpha particle is released as a part of radiation, it is colloquially known as this particle.

What is the nucleus of a Helium atom?

400

What an atom loses when it goes through beta decay

What are an electron and an antineutrino?

OR

What are a positron and a neutrino?

500

What an atom loses when it goes through gamma decay

What is energy?
