BRAINCAKEThe Energy of an Electron
The ionisation energy of an atom is the energy needed to remove an electron, so it is a measure of how strongly that electron is held in its orbital.
The energy of an electron depends on
- the orbital (the energy of p orbitals is greater than the energy of s orbitals)
- the nuclear charge
- the shielding or repulsion of inner shell electrons.
