Question

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/mol. calculate the energy in joules needed to remove one electron in the n=1 state from a hydrogen atom.

N=1 is -1312.04 kj/mol, but i have no idea what the question is asking me? help!!

Answer 1

In other words, how much energy is needed to reach a total of 0 kj/mol

Since n = 1 is -1312.04 kj/mol you will need to add +1312.04 kj/mol to remove one electron from that level.

Or, -1312.04 kj/mol + 1312.04 kj/mol = 0 kj/mol
