Key Topics to Revise
1
Quantum Numbers and Atomic Structure
- Bohr model limitations led to quantum mechanical model of atom
- Orbitals are regions of maximum probability of finding electrons
- Four quantum numbers describe electron characteristics: n, l, m, s
2
Subshell Electron Configuration
- Electrons fill subshells in order of increasing energy: 1s < 2s < 2p < 3s < 3p < 4s < 3d...
- Aufbau principle: electrons occupy lowest energy orbitals first
- Pauli exclusion principle: maximum 2 electrons per orbital with opposite spins
3
Periodic Table Blocks and Trends
- s-block: Groups 1-2, outermost electrons in s subshell (ns¹⁻²)
- p-block: Groups 13-18, outermost electrons in p subshell (ns² np¹⁻⁶)
- d-block: Groups 3-12, electrons filling in d subshell ((n-1)d¹⁻¹⁰ ns¹⁻²)
4
Ionization Enthalpy and Periodic Trends
- Ionization enthalpy = energy needed to remove outermost electron from gaseous atom
- Decreases down a group due to increased atomic size and shielding effect
- Increases across a period due to increased nuclear charge
