Week 5 Basics of Nuclear Physics Flashcards
1
Q
what causes the chemical properties of molecules
A
electronic structure
2
Q
define atomic number and total atomic mass number
A
atomic number = Number of protons = Z
atomic mass = total number of neutrons and protons = A
3
Q
what holds the nucleus together
A
nuclear force
4
Q
what does the binding energy effect
A
directly effects the mass of an atom
5
Q
what is the binding energy equation
A
Δmc^2 = (2mp + Nmn - m(A,Z))c^2
6
Q
why is binding energy per nucleon helpful
A
when plotted against atomic mass it helps show which atoms will undergo fusion and which will undergo fission
