The History of the Atom
Radiation
Nuclear Reactions
100
The particle in the nucleus with a positive charge
What is the proton?
100
This isotope has 12 protons and 13 neutrons
What is magnesium-25?
100
Dalton said that all atoms had this property.
What is indivisibility?
100
A helium nucleus is the particle for this type of radiation.
What is alpha radiation?
100
This is the process of splitting an atom into two or more different atoms.
What is fission?
200
This part of the atom is not found in the nucleus
What is the electron
200
This isotope has 53 protons and 71 neutrons.
What is iodine-124?
200
Rutherford discovered this with the gold foil experiment
What is the nucleus?
200
Uranium-235 will most likely decay by this type of radiation.
What is alpha radiation?
200
When two light nuclei are combined into a heavier one, this nuclear process has occurred.
What is fusion?
300
The mass of the atom is found in this part.
What is the nucleus?
300
This isotope of carbon is used for radiocarbon dating.
What is carbon-14
300
The law of conservation of mass, the law of definite proportions, and the law of multiple proportions were listed together by this scientist.
Who is Dalton?
300
The mass and charge on a gamma ray is this value.
What is 0?
300
The beta decay of carbon-14 produces these two decay products.
What is an electron (beta particle) and nitrogen-14?
400
The particle in the atom that has no charge.
What is the neutron
400
This special name for an isotope has 1 proton and 1 neutron
What is deuterium?
400
The divisibility of the atom was first discovered by this man.
Who is JJ Thomson?
400
This is the order, from most to least penetrating, of the three major types of nuclear radiation.
What is gamma, beta and alpha?
400
The fission of uranium-235 produces tin-125 and this other fission product.
What is Molybdenum-110 (Mo-110) ?
500
The electrons are found here.
What is the electron cloud
500
This isotope of hydrogen has an atomic mass of 3.
What is tritium?
500
This is the major problem with Rutherford's model of the atom.
What is electrons falling into the nucleus?
500
When an isotope has too many neutrons, and one of the neutrons decays, this type of radiation is given off.
What is beta radiation?
500
This fraction of radioisotope is left after the passage of 3 half-lives.
What is 1/8?
