To calculate the first ionization energy of hydrogen, we need to determine the energy required to remove the outermost electron from a hydrogen atom in its ground state.The first ionization energy is the energy required to remove the outermost electron from a neutral hydrogen atom in its ground state (n=1). This process can be represented by the following equation:H(g) → H+(g) + e energy of the emitted photon corresponds to the energy difference between the ground state and the excited state of the hydrogen atom. In this case, the lines converge at , which represents the wavelength of the emitted photon.To calculate the energy of the emitted photon, we can use the formula:E = hc/λwhere E is the energy, h is Planck's constant ( ), c is the speed of light ( ), and λ is the wavelength.Substituting the given values, we have:E = (6.626\times 10^{-34} J\cdot s) \times (3.00\times 10^8 m/s) / (9.12\times 10^{-8} m)E = 2.18\times 10^{-18} JSince the energy of the emitted photon corresponds to the energy required to remove the outermost electron from the hydrogen atom, the first ionization energy of hydrogen is equal to the energy of the emitted photon.Therefore, the first ionization energy of hydrogen is .
