QUESTION 2 (a) The energy required to remove the electron of the hydrogen atom at an unknown energy level (n = x) is 328.0 kJ/mol. (i) Determine the initial energy level (n = x). (ii) Was the hydrogen atom in the ground state or excited state before the electron was removed? (iii) Determine the wavelength (in nm) of the radiation required to remove the electron from the hydrogen atom (where electron is at n = x).
