The Pauling electronegativity and the first ionization energy increase from sodium to chlorine.
The first ionization energy is the energy that is required in order to remove the first electron from an atom in the GAS phase, the second ionization energy is the energy required to remove the second electron from an atom, etc. Ionization energy generally increases for every electron that is removed, and increases from left to right in the periodic table or if moving up the periods. In this case, from the periodic table (or according to Mastering Chemistry) Bromine (Br) has a larger sixth ionization energy than Selenium (Se).
Increasing radius and increasing shield effect.
On the periodic table there is no such order of first and second as asked in the question.
The order is: Cl,S, Si, Al, Na.
Ne (Highest First Ionization Energy) C Be Mg Sr (Lowest First Ionization Energy)

The first ionization energy is the energy that is required in order to remove the first electron from an atom in the GAS phase, the second ionization energy is the energy required to remove the second electron from an atom in the GAS phase. Ionization energy will generally increase for every electron that is removed and increases from left to right in the periodic table and moving up the periods.
Electrons will occupy orbitals having the lowest energy first, and then in order of increasing energy.
Imagine that one electron has already been removed from an atom, the energy used to accomplish this is the 1st ionization energy. Now more energy is needed to remove a 2nd electron. That is the 2nd ionization energy.

is electronic all have electronic config of {Ar} size Ca^2+^<k+<Cl-<s2-< IE S2-<CL-<K+<CA2+
First ionization energy of magnesium = 870/ kj/mol First ionization energy of phosphorous = 589 kj/mol So, magnesium has the larger ionization energy required to pull the first valance electron. Do you know why?
