Define ionization energy and hybridization according to the Cameroon GCE advanced level

Here are the definitions:

Ionization energy is the minimum energy required to remove one mole of electrons from one mole of gaseous atoms in their ground state to form one mole of gaseous positive ions. It is an endothermic process.

For example:
X(g) → X⁺(g) + e⁻

Hybridization is the process of mixing atomic orbitals (typically s, p, and d orbitals) within an atom to form new, degenerate hybrid orbitals. These hybrid orbitals have different shapes and orientations than the original atomic orbitals and are more effective at forming stable chemical bonds, leading to specific molecular geometries.
