History
This experiment lead to the discovery of the atomic nucleus.
The gold foil experiment
The time it takes half of an element to decay
Half Life
How many protons are in potassium?
19
This type of atom has a charge of zero.
Neutral
The least dangerous type of decay
Alpha
These particles were found by experimenting with a cathode ray tube.
Electrons
This particle is made of 2 protons and 2 neutrons
Alpha
The number of electrons are in a chlorine ion with a -1 charge.
18
The name for this element: Am
(pronounced correctly)
Americium
The part of the atom which nuclear chemistry takes place in
The nucleus
This scientist was not really a scientist, but was the first to hypothesize about the existence of atoms.
Democritus
The name of an ion which has lost electrons
Cations
The number of neutrons in Magnesium-26
14
The daughter of 23892U after alpha decay
23490Th
The term for radiation which can damage cells and DNA
Ionizing
Schrodinger discovered that electrons do not travel in perfect circles, but in this manner instead.
Waves
These particles vary in number when an element is in the form of different isotopes.
Neutrons
The number of neutrons in 4220Ca+2
22
What a gamma particle is made out of
Light, Energy or Photons
The type of decay which doesn't change the particles in the nucleus.
Gamma
Bohr observed that elements give off specific colors of light after being subject to electricity and its electrons undergo this process.
Jumping between energy levels (or orbits or rings)
When these two particles are equal in number, the resulting atom is neutral.
Protons and Neutrons
