The successive ionization energies of a certain element are I₁= 589.5 kJ/mol, I₂ =1145 kJ/mol, I₃= 4900 kJ/mol, I₄ = 6500 kJ/mol, and I₅ = 8100 kJ/mol. This pattern of ionization energies suggests that the unknown element is A) K B) Si C) As D) Ca E) S

Question

Quizplus · Accepted Answer

The large jump in ionization energy between I₂ and I₃ suggests the removal of an electron from a stable, filled shell, indicating the element is likely in Group 2, like calcium (Ca).
