Hence, the minimum energy required to free an electron from the ground state of an atom is 13.6 eV. This energy is the ‘Ionization Energy’ of the hydrogen atom. This value agrees with the experimental value of ionization energy too. Now, a hydrogen atom is usually in ‘Ground State’ at room temperature. birchbox man grooming profileWebMar 5, 2024 · In the hydrogen atom, in which the nucleus is just a proton, the ratio M / m is about 1836, so that μ = 0.99946m. For heavier hydrogen-like atoms it is closer to m. Notice that the radius depends on n2, so that, for example, the radius of the n = 2 orbit is four times that of the n = 1 orbit. birchbox man coupon
