Atomic weight is the weighted average of the atomic masses of an atom's naturally occurring
isotopes - correct answer-True
Bonding energy is the energy required to separate two atoms that are chemically bonded to
each other. - correct answer-True
Covenant bonding is bidirectional. - correct answer-True
Cubic Structure Factor BCC - correct answer-Add up to even
Cubic Structure Factor FCC - correct answer-All odd or all even
Edge length BCC - correct answer-4r/sqrt(3)
Edge length FCC - correct answer-2sqrt(2)r
Equation for atomic packing factor - correct answer-((atoms/cell)*(volume/atom))/(volume of
cell)
Equation for measuring Grain SIze - correct answer-D = l/n where
D is average grain diameter
