Web18 aug. 2016 · For He+ there are 2 protons in the nucleus ∴ Z = 2 ∴ I.E. = 2.18 ×10−18 ×22 1 = 8.72× 10−18xJ To convert to kJ divide by 1000 ⇒ I.E. = 8.72 × 10−21xkJ This is the energy required to ionise a single He+ ion. To find the energy required to ionise a mole of ions you need to multiply by The Avogadro Constant which is 6.02 × 1023xmol−1.
