Example for Oxygen (Z=8):
Config: 1s² 2s² 2p⁴
Last electron: 2p⁴ → n=2, l=1, mₗ=+1 or -1, mₛ=+½ (depending on spin alignment) Include the Hund’s rule and Pauli exclusion notes
Every element’s position encodes its ground-state electron configuration. For example:
The periodic trends (atomic radius, ionization energy, electronegativity) all emerge from quantum mechanics. For instance, ionization energy increases across a period because increasing nuclear charge (Z) pulls electrons closer without additional shielding—quantified by Slater’s rules and effective nuclear charge (Z_eff).
Not exactly. For neutral atoms, 4s fills before 3d, but once occupied, 3d drops below 4s. This is a quantum effect of radial nodes and shielding.
