What is Ionization Energy?
- Ionization energy, also known as ionization energy (IE), is the minimal amount of energy needed to free the most loosely bonded electron from an isolated gaseous atom, positive ion, or molecule in physics and chemistry.
- The first ionization energy can be quantified as
Energy + X(g) = X+(g) + e−
- where X is any atom or molecule, e is the removed electron, and X+ is the ion formed when the original atom was depleted of one electron.
What makes ionization energy so crucial?
- The difficulty of removing an electron increases with the ionization energy.
- Ionization energy is therefore a measure of reactivity.
- Because it can be used to forecast the strength of chemical bonds, ionization energy is significant.
