WebJul 1, 2024 · The electron configuration of Al atom is 1s22s22p63s23p1. The second shell has octet ( 2s22p6) while the valence shell has 3 electrons (3s23p1). Mg can achieve octet by losing the 3 valence electrons. The resulting cation is Al 3+ with electron configuration, 1s22s22p6. Exercise 3.3. 1 Write the electron configuration of oxygen atom (Z=8). Although it is sometimes stated that all the electrons in a shell have the same energy, this is an approximation. However, the electrons in one subshell do have exactly the same level of energy, with later subshells having more energy per electron than earlier ones. This effect is great enough that the energy ranges associated with shells can overlap.
