Question

Energy of an electron in the ground state of the hydrogen atom is -2.18x10-18,
Calculate the tonization enthalpy of atomic hydrogen in terms of I mol-1.​

Answer 1

Answer:

13.130×10⁵ J/mol

Explanation:

The ionization enthalpy is the amount of energy required to remove an electron from ground state to infinity. The energy of electron in the ground state is −2.18×10^(-18) J

The energy of electron at infity is zero.

The energy required to remove electron = 0 - [-2.18 × 10^(-18)J].

= 2.18×10^(-18) J

To remove 1 mole of electrons, the amount of energy required = 2.18×10^(-18) ×6.023×10²³

= 13.130×10⁵ J/mol
