Elaborate on the differences between metals and noble gases. a) noble gases have a full shell of valence electrons while metals have only a few valence electrons. b) valence electrons are different - metals have a full shell while noble gases have less than half a shell. c) metals have a nearly full shell of valence electrons while noble gases have a half shell of valence electrons. d) all electrons are different - noble gases have a full shells while noble gases have greater than half shells.

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
