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...

In two-photon ionization spectroscopy, the combined energies carried by two different photons are used to remove an electron from an atom or molecule. In such an experiment a aluminum atom in the gas phase is to be ionized by two different light beams, one of which has wavelength 395 nm. What is the maximum wavelength for the second beam that will cause two-photon ionization? Hint: The ionization energy of aluminum is 577.6 kJ/mol nm?

Why is the first ionization of aluminum less than the first ionization of magnesium? Select all that apply. A. The last valence electron of magnesium ends the occupation of the 3s subshell. B. The statement is incorrect because the general trend left to right in a row is for the effective nuclear charge to increase. C. The 3s electrons shield the 3p electrons from the nuclear charge. D. The last valence electron of aluminum begins the occupation of the 3p...
