This is what holds the nucleus of an atom together.
What is the Strong Nuclear Force?
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)
100
In a single half- life, and element decays by this much.
What is half of an element?
100

This particle was discovered by JJ Thomson with his famous Cathode Ray Experiment.

What is an electron?

100
This particle is the opposite particle of an electron.
What is a positron?
200
This force is what causes atoms to decay.
What is Weak Nuclear Force?
200
This particle is a product of nuclear decay, and denotes a loss of two protons.
What is a Beta Particle?
200
The scientist who famously discovered half life.
Who is Ernest Rutherford?
200
This is where the word 'Atoms' was derived from (hint: it came from the Romans)
What is 'Atomos'?
200
This particle is the antiparticle of a proton.
What is an antiproton?
300
When Strong Nuclear Force is utilized to generate energy, it is through this process.
What is Nuclear Fission?
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 an Alpha Particle?
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?
300

The experiments of Michelson and Morley showed that light was not affected by ______.  

What is ether

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
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?
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?
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?
400
This scientist determined that electrons exist in stable energy levels, and change energy levels by disappearing and simultaneously reappearing in the energy level above or below the previous one.
Who is Niels Bohr?
400

While atoms are generally considered the smallest divisible particle that exists, they are actually made of smaller particles called by these names.

What are quarks?

500
This is what the decay of large or unstable elements is called, and is a principal part of Nuclear Physics.
What is Radioactivity?
500
This is the particle used to initiate nuclear fission events, and can cause massive chain reactions resulting in extremely large amounts of energy, provided the the material is unstable and fissile enough.
What is a neutron?
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

500
Ernest Rutherford determined the difference between these particles, and is famous for determining that these types of radiation even exist.
What is alpha and beta radiation?
500
