Homework Help: College Chemistry

Posted by Bach on Wednesday, April 28, 2010 at 1:23am.

In energy terms, ionization of an electron in an atom corresponds to the transition from whatever quantum state the electron is in to an energy of 0 KJ/mole. Calculate the energy in joules needed to remove one electron in the n=1 state from a hydrogen atom.

I know En of 1 = -1312 KJ/mole
so delta En = | 0+1312 |= 1312 KJ/mol

1312 KJ/mol x 1mol/6.022 x 10^23 particles x 1000joules/KJ

is this the correct why to approach this problem? Are my steps correct?
