Cheat Sheet
- Symbols & Atomic Numbers (21 - 30) -
Memorize the chemical symbols Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn alongside their atomic numbers 21 to 30. Use the mnemonic "Scary Tiger Viciously Charges, Monkeys Flee, Cows Nap, Cuddly Zebras Zoom" to lock in each element's place on the periodic table (IUPAC).
- Electron Configuration Patterns -
Elements 21 - 30 fill the 3d subshell after 4s, producing configurations like Sc [Ar] 4s2 3d1 up to Zn [Ar] 4s2 3d10. Practice writing each to see how the Aufbau principle leads to exceptions like Cr and Cu (e.g., Cr is [Ar] 4s1 3d5).
- Oxidation States & Colors -
Review common oxidation states: V ranges from +2 to +5, Mn from +2 to +7, and Fe typically +2/+3. Refer to university spectra data showing Mn2+ (pale pink) and Cr3+ (green) to connect oxidation state with compound color (source: Royal Society of Chemistry).
- Periodic Trends (Atomic Radius & Ionization Energy) -
Across elements 21 - 30, atomic radius decreases and ionization energy generally increases due to higher nuclear charge. Comparing values (e.g., Sc 162 pm vs. Zn 139 pm radius) from NIST tables cements understanding of periodic trends.
- Shortest Element Names -
Among the first 30 elements, Iron and Zinc each have the shortest English names (4 letters). Use this trivia as a fun anchor for your first 30 elements quiz and to reinforce recall of Fe (26) and Zn (30).
