a) the first ionization energies (IE) of hydrogen and helium are about 1300 kJ/ mol and 2300 kJ/ mol respectively. Yet the electron removed from both of these originated in a 1s orbital. Explain in 1-3 sentences the large IE difference observed between these elements . b) Another particulary interesting exception to the trend in 1st ionization energy is found by comparing N and O. The 1st IE is higher for N than O, even though O has 1 more...
