Part A Use the building-up principle to obtain the electron configuration of the ground state of iron. (Express your answer as a series of orbitals. For example, the electron configuration of Li would be entered in complete form as 1s2 2s1 or in condensed form as [He]2s1.) Part B Iron is a Group 8B element in Period 4. What would you expect for the valence-shell configuration of iron? (Express your answer as a series of valence orbitals. For example, the valence-shell...
