Q. As we know that when ever there is a transfer of electrons, their is also a transfer of mass from1 atom to the other, but we also know that atomic mass of an atom = no. of proton + no. of neutron and as we can see that electron does not play any role in determining atomic mass then how can we say that their is transfer of mass?
