🗑
|
||||
| beta particle | high speed negatively charged electron emmited by a radioactive nucleus in beta decay
🗑
|
||||
| gamma particle | rays of high energy, short wave radiation emitted from nuclei of atoms
🗑
|
||||
| isotopes | different atoms of a particular element that have the same number of protons but different number of neutrons ( different atomic mass )
🗑
|
||||
| light | one form of radiation that is visible to humans
🗑
|
||||
| mass number | the total number of protons and neutrons found in the nucleus of a atom
🗑
|
||||
| radiation | as high energy rays and particles emitted by radioactive sources
🗑
|
||||
| radioactivity | release of high energy particles and rays of energy from a substance as a result of changes in the nuclei
🗑
|
||||
| proton | a sub-atomic particle that has a positive electric charge ( 1+ )
🗑
|
||||
| neutron | a sub-atomic particle that does not have a electric charge
🗑
|
||||
| electron | a sub-atomic particle that has a negative electric charge ( 1- )

| Ernest Rutherford | A canadian chemist who received a nobel prize for research into chemistry into radioactive substances.
🗑
|
||||
| Alpha decay | emission of a alpha particle ( 1- ) from a nucleus
🗑
|
||||
| beta decay | a neutron changes into a proton ( 1+ ) that stays in the nucleus, and a electron ( 1- ) that shoots out from the neucleus with lots of engergy
🗑
|
||||
| gamma decay | results from a redistribution of energy within the nucleus giving off a high energy gamma ray as the isotope falls from a high energy state to a low energy state
🗑
|
||||
| nuclear equation | a set of symbols that indicates changes in the nuclei of atoms during a nuclear reaction
🗑
|
||||
| Radio isotopes | natural or man-made isotopes that decay into other isotopes relasing radiation
🗑
