    1. The periodic table is arranged in the order of added electrons, and electrons fill the “4s” section before the “3d” section.
    2. The “3d” section is put with its corresponding energy level because the electrons will fill lower values of “n” first always.
    3. The Pauli Exclusion Principle disallows electrons from filling the “3d” section before the “4s” section.
    4. This is just for historical reasons, and the “3d” section would be placed higher if the periodic table were recreated now.
    5. Electron configuration notation dictates that the energy level n come before the angular momentum quantum number.
    1. By referring each electron configuration from the prior noble gas.
    2. By referring each electron configuration from the prior angular momentum quantum number.
    3. By omitting the angular momentum quantum number when it can be easily deduced.
    4. By omitting the energy level quantum number when it can be easily deduced.
    5. By listing the energy levels independently of the other quantum numbers.
    1. [Ar]4s1
    2. [Ar]3s4
    3. [Ar]4p1
    4. [Ar]3s24p4
    5. [Ar]5d2
    1. To keep with the other noble gases, which have their outer electron shells filled.
    2. Each row in the periodic table must span the full width.
    3. The Pauli Exclusion Principle disallows it from remaining in the s section.
    4. The n=0 energy level can only hold one electron.
    5. The 1s section of the periodic table cannot have its outer shell filled.
