Cheat Sheet
- Periodic Trends Mastery -
Understand how atomic radius decreases across a period and increases down a group due to effective nuclear charge and electron shielding (Chemistry LibreTexts). Recognize that ionization energy and electronegativity generally increase from left to right but decrease top to bottom, helping predict reactivity and bond types. Use the mnemonic "FONCl BrISCH" to recall the most electronegative elements (Fluorine, Oxygen, Nitrogen, Chlorine, Bromine, Iodine, Sulfur, Carbon, Hydrogen).
- Four Quantum Numbers -
Review the principal (n), angular (l), magnetic (ml), and spin (ms) quantum numbers, which uniquely describe each electron's state (Atkins' Physical Chemistry). Remember that n defines energy level, l (0 to n - 1) defines subshell shape, ml ( - l to +l) defines orbital orientation, and ms (±½) defines spin. Practice by assigning quantum numbers to electrons in carbon's 2p orbital: n=2, l=1, ml= - 1,0,+1, ms=±½.
- Electron Configuration Rules -
Apply the Aufbau principle, Pauli exclusion principle, and Hund's rule to build configurations from hydrogen onward (IUPAC Recommendations). For example, oxygen's configuration is 1s² 2s² 2p❴, filling each 2p orbital singly before pairing. A quick check: the sum of superscripts equals the atom's atomic number, ensuring accuracy.
- Orbital Shapes & Subshells -
Visualize s (spherical), p (dumbbell), d (cloverleaf), and f (complex) orbitals to predict bonding angles and molecular geometry (University of California Chemistry). Sketch or use 3D models to see nodal planes and lobes. As a tip, link p-orbital lobes to "dumbbells" you might lift at the gym to remember their shape!
- Effective Nuclear Charge & Shielding -
Calculate Zeff ≈ Z - S using Slater's rules to estimate how strongly an electron feels the nucleus (University of Oxford). Higher Zeff means smaller atomic radius and higher ionization energy. Compare elements in the same period to see how inner electrons shield outer ones differently.
