|
Nobel in Chemistry
Studied chem. for radium(got radioactivity) |
|
|
Irene Curie
|
Produced first synthetic radioactive isotope(p-30), by bombarding Al-27 with alpha particles)

|
|
What is the difference between natural and iniduced radioactivity?
|
Natural: Unstable nuclei trying to become stable
Induced: Bombarding stable nucleus to make unstable ones |
|
|
Artificial decay releases/does not release
|
is never alpha or beta, but can release gamma
|
|
|
Induced Radioactivity
|
positron decay, electron capture, nuclear bombardment
|
|
|
Enrico Fermi
|
built first nuclear reactor
|
|
|
Alpha Emission
|
Give off hydrogen 4, 2
|
|
|
Beta Emission
|
Nuetron becomes proton, and electron shot off
|
|
|
Nuclear Bombardment
|
Atoms shot at nuclides to cause different products
|
|
|
Positron Decay
|
Beta-Positive Decay:
Proton becomes a nuetron, and positive electron is shot out |
|
|
Electron Capture
|
Electron captured:
captures inner electron, and proton becomes a nuetron |
