using only the periodic table, write the expected ground-state electron configurations for:
a. element number 116
b. an element with three unpaired 5d electrons
c. the halogen with electrons in the 6p atomic orbitals

    i still don't understand.
    especially part a, because element number 116 is not on the periodic table.
