Answer #1

(a) If there wouldn't have the Pauli exclusion principle then all the electron could occupy the lowest energy level, i.e, all 20 electrons of the calcium atom should go to orbitals. Then, the electronic configuration would have been

(b) The atomic number for Ca is 20. Now if the electronic spin quantum number was absent and all other princiles of quantum mechanics remained valid including the Pauli's exclusion principle, then the electronic configuration of Ca would have been
