Discovery of Radioactivity
Wilhelm Roentgen
Isotopes with unstable Nuclei
Process where a nucleus releases energy
Decay
A too heavy nuclei
Unstable
The type of energy used in mass-energy formula
Joules
Marie Curie
Alpha particles
Reduces both amount of protons and neutrons
Alpha decay
The split of a nucleus into fragments
Nuclear fission
Albert Einsteins most famous equation
E=mc²
Produce spontaneous emissions
Uranium salts
Particle not affected by electric field
Gamma rays
Time needed for half of a radioisotope nuclei to decay
Half-life
Combination of multiple nuclei
Nuclear Fusion
The conversion of one element to another
Transmutation
Marie Curie
This decay lowers the amount of neutrons in a nucleus
Beta decay
Nuclear power plants use this
Fission
Finding the age of an object by determining the remaining radioisotope
Radio chemical dating
Pitchblende
Damaging to living tissue
Gamma rays and X-rays
Uranium-235-->Thorium-231
Alpha radiation
Fusion reactions can be known as this
Thermonuclear reactions
Radiochemical dating used to figure out the age of organic materials
Carbon dating
