Ionization energy for the removal of an electron from a neutral atom can be calculated, by substituting, the orbit number of the electron before transition as 鈥榥 1 鈥?and orbit number of the electron after transition as 鈥樷垶’ (infinity) as 鈥榥 2 鈥?in Bohr鈥檚 energy equation.

Ionization energy, or ionisation energy, is the energy required to remove an electron from a gaseous atom or ion. First ionization energy is the energy required to remove one electron from the gaseous atom First Ionization for Hydrogen: H (g) 鈫?H +(g) + e – First Ionization for Carbon: C (g) 鈫?C +(g) + e –

The energy essential to take away an electron from a gaseous atom A or a gaseous molecule AB is titled as ionization energy. Referring to the following equation. A mass spectrometer can determine the ionization energy. The ionization energy or potential is therefore sometimes also called the 鈥渢hreshold鈥?or 鈥渁ppearance鈥?energy or potential.

Ionization potential for hydrogen can be calculated using the following equation: E = hcRH (1/n 2), where E is energy of the electron (or the amount of energy it takes to remove the electron, ionization energy) h is Planck鈥檚 constant = 6.626 * 10 -34 Js (joules*seconds)
