An isotope is | a different form of the same elements |
How are isotopes different | Isotopes will have a different number of neutrons |
Isotopic frequency | The abundance of an isotope in the sample of an element |
What is a mass spectrometer | An instrument used to measure the mass and abundance of isotopes |
What is radioactive decay | The spontaneous decay of unstable isotopes |
Nuclear radiation | When the nucleus of a radioisotope emit's energy as it decays |
what is an Alpha particle | A product of nuclear decay that is positvely charged |
What is a Beta particle | A product of nuclear decay that is negatively charged |
Gamma rays are | highend electromagnetic radiation |
What is a radioisotope | An isotope that decays to form two or more smaller nucleus and radiation |
If something is radioactive that means it | has the potential to emit nuclear radiation upon decay |
What is atomic mass | the weighted average of the mass of naturally occuring isotopes of an element |
