My goodness, Michael, Kelly, Christina -- or whatever you name is -- you just posted 8 chemistry questions. Do you know how to start any of them?

Hi sorry - We have been working together trying to figure them out. and no we don't know

Add mass electrons, mass neutrons, mass protons to find sum, subtract from the mass of the atom to find the mass defect. Delta E = delta m*c2
Delta E/number of nucleons = energy/nucleon.
