    Can someone explain the oxidation selection on calculating electrons as noted

    Ok. I am studying my notes and have a question on # of p,f and e. Atom of Nitrogen-14 = 14 over 7 N p=7 n=7 e=? net charge/oxdation 2,+-3,4,5 Atom of Iron -256 = 56 over 26 FE p=26 n=30 e?? net charge 2,3 Atom of Uranium-256= 236 over 92 U p=92 n=144 e= net charge 3,4,5,6 I am to...
