Term
What is the energy equivalent (in MeV) of the mass of an electron?
Definition
0.511 MeV
Term
What is the energy equivalent (in MeV) of the fundamental mass unit?
Definition
930 MeV
Term
E=mc^2
Definition
E is energy, m is mass, and c is the speed of light in a vacuum or 3x10^10 cm/sec
Term
What is the maximum number of e- in a shell?
Definition
2n^2
Term
Define Nuclide
Definition
any combo of protons and neutrons and nucleon arrangement with a measurable lifetime
Term
Isotopes have the same Z, but different A.
Definition
Isotones have the same N, but different A.
Term
Isobars have the same A, but different Z. (top left number same, bottom left is dif.)
Definition
Isomers have the same A and Z, but a different nucleon arrangement such as 99Tc and 99mTc
Term
The energy for nuclear force is provided by what?
Definition
the Nuclear Binding energy
Term
All electromagnetic radiations travel at the same what?
Definition
velocity
Term
What is the difference between ionizing radiation and excitation?
Definition
Excitation- the electron moves to a different energy state. Ionizing radiation strips the electron and transfer of radiation from electron to atom
