Scientists
I was the head of the Manhatten Project. They even made a movie about me.
Who is J. Robert Oppenhiemer?
The number that shows how many protons and electrons are in a neutral element.
What is the Atomic Number?
During this process atoms naturally break down to form different elements than what was at the beginning.
What is Radioactive Decay?
In the sun this fundamental force overcomes the electromagnetic force to fuse atoms.
What is Gravity?
These particles make up protons.
What are Quarks?
This duo was the first to use neutrons to split an atom.
Who are Otto Han and Fritz Strassman?
Elements are arranged into this category. It shows you how many valence electrons an element has.
What are groups?
This fission bomb assembly "shoots" one piece of sub-critical uranium into another with a chemical explosive.
What is the Gun Assembly Method?
What is Helium?
These occupy the outermost shell or cloud around the nucleus of an atom.
What are Valence Electrons?
Who is Albert Einstein?
This block is the most stable of all the elements.
What are the Nobel Gasses?
This sub-atomic particle is used to split an atom.
What is a neutron?
This fission assembly type is used to start the explosion for fusion-based weapons.
What is the Implosion Assembly Type?
Electrons and neutrinos belong to this group of sub-atomic particles.
What are Leptons?
I coined the term "fission" while I was on the team that discovered the element Protactinium.
Who is Lisa Meitner?
Elements that are in the same ______ have similar properties.
What are blocks or families?
Discovered in 1917 this "long-lived" element last several minutes before breaking down. Making it ideal for fission experiments.
What is Protactinium?
Its light atomic mass makes it fuse easily with other similar atoms. Making it ideal for the fusion part of a thermonuclear weapon.
What is Hydrogen?
The fundamental force that binds quarks together to form protons an neutrons.
What is Strong Force?
The duo headed the project that led to the first Hydrogen bomb.
Who are Edward Teller and Stanislaw Ulam?
Hydrogen sits atop THIS block, but it actually belongs to THIS block.
What are Alkalai Metals and Nonmetals?
After one atom is split this occurs and splits more atoms. The results are highly explosive.
What is a chain reaction?
Atomic weapons are measured in kilotons, but thermonuclear weapons are measured in this. One is equal to 1000 kilotons.
What are Megatons?
The Fundamental Force that changes protons into neutrons.
What is Weak Force?
