Energy of an electron in the ground stat...

Energy of an electron in the ground state of the hydrogen atom is `-2.18xx10^(-18)J`. Calculate the ionization enthalpy of atomic hydrogen in terms of J `mol^(-1)`.

Text Solution

Verified by Experts

Ionization enthalpy of hydrogen atom `=-2.18xx10^(-18)J//"atom"`
Ionization enthalpy in terms of J/mol `=-2.18xx10^(-18)xx6.02xx10^(23)J//mol= 13.12xx10^(5)Jmol^(-1)`
