A fundamental relationship of electrostatics states that the en-ergy required to separate opposite charges of magnitudes Q1and Q2 that are the distance dapart is proportional to Q1XQ2/d .Use this relationship and any other factors to explain the fol-lowing observations: (a) the IE₂ of He (Z=2) is morethantwice the IE₁ of H (Z=1); (b) the IE₁ of He is less than twice the IE₁ of H.
