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.
