The ionization energy of hydrogen is 13.6 eV. What is the energy required to excite an electron from n = 1 to n = 3?
Q1. The ionization energy of hydrogen is 13.6 eV. What is the energy required to excite an electron from n = 1 to n = 3?
Answer: 12.09 eV
Explanation: Using the Bohr model energy formula: ΔE = 13.6 eV (1/n²_initial - 1/n²_final), ΔE = 13.6 (1 - 1/9) = 12.09 eV.
