The ionization energies for a hypothetical element are listed below. Based on these ionization energies, identify which group the element would be from on the Periodic Table.

IE₁ (kJ/mol)	IE₂ (kJ/mol)	IE₃ (kJ/mol)	IE₄ (kJ/mol)	IE₅ (kJ/mol)	IE₆ (kJ/mol)
600	1200	7300	9580	12,600	14,640

Expert Solution

According to the given trend of ionization energies the first 2 electrons are removed easily with less expenditure of energy which means that this element has 2 valence electrons.

Third and successive electrons requires enormous amount of ionization energies which means that these electrons are removed from very stable noble gas configuration.

This element has 2 valence electrons and it must belong to group 2 of the periodic table.

Answer -- Group 2

Explain how the successive (first, second, third, etc) ionization potentials change in each atom.3. For most atoms, there are one or two huge jumps in the ionization potential. Explain why these occur. In aluminum, explain these huge increases using the valence electrons.4. Explain any trend you observe when looking at only the first ionization energies of each of the 13 elements.
