6. Gallium arsenide (GaAs) is used in the red lasers of bar-code readers. (a) Write the full, ground state electron configuration of both gallium and arsenic. (b) Identify how many valence electrons each atom has. (c) Using electron configurations, show what the most likely ions to form would be for both Ga and As. (d) Predict whether (i) the most likely ion for gallium be smaller or larger than its neutral atom and (ii) the arsenic ion be smaller or larger than its neutral atom. Explain your predictions.

The 2s and 2p energy levels are different. Which of thefollowing is the best explanation for why this is the case?(i) The 2s and 2p energy levels have different energies inthe hydrogen atom, so of course they will have differentenergies in the sodium atom, (ii) The energy of the 2porbital is higher than that of the 2s in all many-electronatoms. (iii) The 2s level in Na has electrons in it, whereasthe 2p does not.
