Ionisation Enthalpies
When electrons have been removed from an atom or molecule, it's been ionised.
The energy needed to remove the first electron is called the first ionisation enthalpy.
We define the first ionisation enthalpy of an element as the energy needed to
remove one electron from every atom in…

Factors Affecting Ionisation Enthalpy
Negative electrons are held in their shells by attraction to the positive nucleus.
To form a positive ion, energy must be supplied to an electron to overcome the
attraction from the nucleus.
Electrons in the outer shell are removed first since they experience the least nuclear…
