Answer 1

Answer:

ionization enthalpy is the energy which is required to remove the electron from the ground state of the atom to infinity . the energy of the electron at infinty is zero = 2.18 *10 — 18 j . therefore - 0 = - 2.18 * 10 _ 18 joules = 2.18 * 10 * - 18. now to remove the one mole of electron from hydrogen atom =2 .18 *10 *-18 multiply 6.022*10-23 = 1.312 ionization enthalpy of hydrogen atom . *answer*
