Electron configuration

Electron configurations of atoms and ions up to Z = 36 in terms of shells and sub-shells (orbitals) s, p and d. Define ionisation energy and definition first ionisation energy Equations for first and successive ionisation energies Explain first ionisation energy trends Explain how first and successive ionisation energies in Period 3 (Na–Ar) and in Group 2 (Be–Ba) give evidence for electron configuration in
