Consider the following changes A → A+ + e- : E1 and A+ → A2+ + e-: E2 The energy required to pull out the two electrons are E1 and E2 respectively. The correct relationship between two energies would be (a) E1 < E2 (b) E1 = E2 (c) E1 > E2 (d) E1 ≥ E2

Correct answer: (a) E1 < E2 Explanation: IE1 is always less than IE2.

Consider the following changes

A → A⁺ + e^- : E₁ and A⁺ → A²⁺ + e^-: E₂

The energy required to pull out the two electrons are E₁ and E₂ respectively. The correct relationship between two energies would be

(a) E₁ < E₂

(b) E₁ = E₂

(d) E₁ ≥ E₂
