Nucleus basics
It's natural!
Thank you, Lise
Just use hydrogen
Bonus
100
The atomic number tells you.
What is the number of protons in an element?
100
It releases high-energy electromagnetic radiation from the nucleus.
What is gamma decay?
100
When a large unstable nucleus splits into two smaller daughter nuclei.
What is (nuclear) fission?
100
When smaller nuclei join together to form one larger nucleus.
What is (nuclear) fusion?
100
That's what the m stands for in E=mc2
What is mass?
200
These are atoms that have the same number of protons, but different numbers of neutrons.
What are isotopes?
200
Made of 2 protons, 2 neutrons.
What is an alpha particle?
200
When one of these has to hit a Uranium-235 nucleus, the nucleus falls apart.
What is a neutron?
200
This word refers to the high temperatures needed for fusion to take place.
What is "thermonuclear"?
200
An element discovered by Marie Curie, and used to murder Alexandr Litvenenko
What is Polonium?
300
It's the glue that holds a nucleus together.
What is the strong nuclear force?
300
These both change a radioactive isotope into a new and different element.
What are alpha and beta decay?
300
The minimum amount of fissionable material needed for a chain reaction to take place.
What is critical mass?
300
These "heavy" isotopes of hydrogen have a neutron in addition to a proton.
What is deuterium?
300
This form of uranium is purified and can be transported. In spite of the name, you wouldn't want this on your birthday.
What is yellow cake?
400
That's how many neutrons are in Barium-130
What is 76?
400
This results from the beta decay of Cesium-137.
What is Barium-137?
400
The equipment used to enrich uranium.
What is a centrifuge?
400
A special "fourth state" of matter found at the center of the sun and other stars
What is plasma?
400
A decay product of natural uranium ores, this gas could be leaking into your basement.
What is radon?
500
The discoverer of x-rays.
Who was Roentgen?
500
This detector of radiation makes a distinctive tik-tik-tik sound when decay particles hit it.
What is a Geiger counter?
500
The amount of energy converted from mass in a typical U-245 fission event.
What is 200 million electron volts?
500
0.7 % of this is converted to energy using fusion, compared to just 0.1% in fission.
What is mass?
500
This special chamber uses electromagnetic fields to hold plasma in place (at 150 million degrees C!)
What is a tokamak?
