Among the following, which one equals minimum excitation potential of Bohr's first orbit in hydrogen atom?

We know, Excitation energy =e (Excitation potential) ....Excitation energy of Bohr's first orbit in hydrogen atom is minimum when transition of electron is from n = 1 to n = 2.Minimum Excitation energy in hydrogen atom, (Emin)=E2−E1Emin=−3.4−(−13.6)eVEmin=10.2eVSo, minimum Excitation potential=EmineMinimum excitation potential of Bohr's first orbit = 10.2 V
