SUMMARY
The ionization energy of a helium atom is established at 24.6 eV. The second ionization potential (IP2) can be calculated using the formula IP2 = IP1 * Z², where Z is the atomic number. However, this approach is only valid for hydrogen-like species, such as He+, which has one electron. The Bohr model is not applicable to the neutral helium atom due to its two electrons, leading to potential inaccuracies if applied directly to He.
