Final answer:
The ionization energy for helium is not explicitly provided; however, it is known to be higher than that of hydrogen (1.31 x 10⁶ J) due to helium's larger nuclear charge. Specific ionization energy would require empirical data or a conversion from eV to joules.
Step-by-step explanation:
The ionization energy of an element is the energy required to remove an electron from an atom in its gaseous state. For hydrogen, with one electron and one proton, the ionization energy is given as 1.31 x 10⁶ J (option a). The ionization energy for helium, a noble gas with two protons in its nucleus and two electrons, is significantly higher compared to hydrogen due to the increased nuclear charge that more strongly attracts the electrons. According to the information provided, the ionization energy required to remove an electron from the He+ ion (helium atom that has already lost one electron) is -54.4 eV, which can be related to the amount of energy in joules. However, the precise ionization energy value for neutral helium is not given in the provided material.
To determine the ionization energy for helium, we would need information analogous to that of hydrogen or an empirical value based on experimental data. Hence, without specific information or a direct conversion factor, it is not possible to accurately state the ionization energy for helium solely from the information given. However, we can confidently state that the ionization energy of helium will be higher than that of hydrogen due to its greater nuclear charge and the higher energy required to overcome the attraction between the nucleus and the electrons.
