General Chemistry Final Exam Questions Correctly Answered. Atomic Number vs mass number vs. atomic mass vs. atomic weight vs. molecular weight - CORRECT ANSWER atomic number-Z=protons mass number- A=sum of protons and neutrons -atomic mass: mass number ^^ -atomic weight: weighted average of naturally occurring isotopes (12.011) -molecular weight: add up the atomic weights of each element in a compound subatomic charges aka charge of an electron - CORRECT ANSWER e= 1.6 x 10^-19 1 ele...

what makes a material conductive - ANSWER Reasoning for conductivity: delocalized 'sea' of electrons loosely bonding the layers together. These delocalized electrons can all move along together - making graphite a good electrical conductor. atomic number - ANSWER Z the number of protons in the nucleus of an atom atomic mass unit - ANSWER a unit of mass that describes the mass of an atom or molecule measured in amu
