What is Gamma decay?
By shooting Alpha particles at gold foil, Rutherford was able to discover the existence of this
What is the nucleus (protons)?
The number of protons in an atom gives the atom this number on the periodic table
What is the atomic number?
The sum of the neutrons and protons of an atom gives us this
What is the atomic mass?
If the number of electrons changes in an atom, a new one of these is formed

The atomic number increases by 1 in this type of nuclear decay
What is Beta decay (minus)?
His Uncertainty Principle states that it is impossible to know for sure the location or speed of electrons
Who was Heisenberg?
If the number of protons of an atom could somehow change, it would create a new one of these
What is an element?
If the number of neutrons in an atom changes, a new one of these is formed
What is an isotope?
In a neutral atom, the number of electrons must be the same as this other atomic particle
A high-energy electron is released in this type of decay
