Atoms Flashcards
Daltons model
Big dense sphere
Thompsons model
Electrons are smaller than atoms
Rutherford model
Nucleus is positive
Bohrs model
Electrons move around nucleus
AMU
Percent times mass plus percent times mass
Alpha decay
Used when there is too many protons and neutrons
Beta decay
Too many neutrons
Positron emission
Too many protons
Gamma decay
Too much energy
Radiation
Transmission of energy in the form of waves
Radioisotope
Unstable form of a chemical element that releases radiation
Unstable element that releases radiation (chemical)
Isotope
2 or more types of atoms that have a different number of neutrons
Releases energy when atoms split
Fission
Adds neutrons
Fission
Smaller atoms at the end
Fission
Releases energy when atoms are joined
Fusion
Due to high pressure and heat can’t be found in nature
Fusion
Can be found in nature
Fission
Nuclear reactions
Both
Produce a lot of energy
Both
Particles added in the beginning and particles released in the end.
