8 (5 points). Toto the canine astronaut is piloting a starship 178,000 light years away from Earth. He stumbles upon what he believes is the mythical "Leg Bone Asteroid", and "beams fore. The science officer, Youngbloodz, elucidates spectroscopically that anew element has been discovered, and names it Akonium She determines that succe ionization energies in attojoules (al)per atom for the new elementare J0.507.12, 1017:l3 4.108: L,5.074 1s, 6.147: 1s, 7.903: 12,8.294/Based exclusively upon logic,to wha the periodic table does this new element probably belong? What atomic sym bol is most appropriate for this new element? Mt) -+ |E1--7 Mtg) (*) Atomic SumboH

Explanation / Answer

Identification of element group

The value of I3 (third ionization energy) is much greater than I2(second ionization energy)

this trend is seen in case of alkaline earth metal elements.

Atomic symbol applicable for the element = Ak

Family of periodic table = Group IIA (Alkaline earth metal series)
