Homework Help: Chemistry

Posted by Anonymous on Tuesday, June 8, 2010 at 12:47pm.

Calculate the mass defect and the binding energy/nucleon of the nuclide 9/4 Be, which has a mass of 9.01218224 amu. The mass of the proton is 1.00726747 amu and the mass of the neutron is 1.00866490 amu.

I've gotten this far...

mass of proton + mass of nuetron = 2.01594137. but how do i find the mass of the electron?

Then, how do I find the number of nucleons so that I can divide DeltaE by the number of nucelons to give me the binding energy
