Hey please define first ionization energy and second ionization energy according to the Cameroon GCE advanced level

Here are the definitions:

First ionization energy is the energy required to remove one mole of electrons from one mole of gaseous atoms to form one mole of gaseous 1+ ions. It is an endothermic process.

For example:
X(g) → X⁺(g) + e⁻

Second ionization energy is the energy required to remove one mole of electrons from one mole of gaseous 1+ ions to form one mole of gaseous 2+ ions. This is also an endothermic process and is always greater than the first ionization energy for the same element.

For example:
X⁺(g) → X²⁺(g) + e⁻
