The ionization energy of a hydrogen-like ion with Z = 2 is 54.4 eV. What is the energy of the ground state?
Q1. The ionization energy of a hydrogen-like ion with Z = 2 is 54.4 eV. What is the energy of the ground state?
Answer: -54.4 eV
Explanation: For a hydrogen-like ion, En = -13.6 * Z² / n² eV. For Z = 2 and n = 1, E1 = -54.4 eV.
