If an atom is Neutral in charge (not an Ion) then the number of electrons should equal the number of protons.  42 protons = 42 electrons
   The number of Neutrons is generally determined by subtract the number of Protons from the Atomic Weight.  96 - 42 = 56
   Number of Valence electrons is 4d5 + 5s1 = 6
   Number of electrons in the 3rd shell is 18 (seemed too easy. Did I not understand n = 3 shell?)

Thank you!!
