The minimum energy required to ionize a hydrogen atom in the n = 2 state is -1.51 eV. Option B is corect.
What is hydrogen?
The chemical element hydrogen has the atomic number 1 and the symbol H. The smallest element is hydrogen.
The second excited state matches n=3. The minimum energy required to ionize a hydrogen atom in the n = 2 state is;
[tex]\rm E= - \frac{13.6}{n^2} \\\\ \rm E= \frac{13.6}{3^2} \\\\ E= - \frac{13.6}{9} \\\\ E= -1.51 \ eV[/tex]
The minimum energy required to ionize a hydrogen atom in the n = 2 state is -1.51 eV
Hence, option B is corect.
