Chemical Nomenclature & Classification Battle
2–4 Players / Teams 25–35 Min
Mission Objective: Outscore rival chemists by correctly distinguishing ionic from molecular compounds, matching chemical formulas to IUPAC names, and forging accurate chemical structures.
Game Setup
Cut out all 24 compound cards (12 Formulas, 12 Names).
Each player receives a printed Bond Clash Player Worksheet .
Shuffle the deck and place it face-down in the center Draw Crucible .
Establish the Ionic Vault (left) and Molecular Chamber (right) discard zones.
3 Core Gameplay Modes
1 Speed Sort Dash (Warm-Up)
Flip cards one by one. First player to call "Ionic!" or "Molecular!" with valid chemical reasoning banks the card (+10 pts). False calls cost -5 pts!
2 Formula-Name Fusion Duel
Deal 4 cards to each player. Players hunt matching formula-name pairs on the table. Claiming a verified match banks +25 pts.
3 Formula Forge Challenge
Draw a card. If it is a name, write the formula on your sheet. If it is a formula, write the name. Full ion charge check required for ionic!
The Chemist's Codex
Ionic Compounds e⁻ Transfer
Formed by Metal + Nonmetal or Polyatomic Ions (e.g., NH₄⁺, SO₄²⁻).
Charges must sum to zero (criss-cross method).
Use Roman numerals for transition metals with multiple oxidation states (e.g., Iron(III) oxide).
NEVER use Greek prefixes (no "mono", "di", "tri")!
Molecular Compounds e⁻ Shared
Formed exclusively between Nonmetal + Nonmetal atoms.
Covalent bonding via shared electron pairs; no charges to balance.
MUST use Greek prefixes to indicate atom quantities:
1: mono- 2: di- 3: tri- 4: tetra- 5: penta-
Scoring Matrix
Action / Accomplishment Points Correct Bond Classification (Ionic vs Molecular) +10 pts Correct Formula ↔ Name Match Claim +25 pts Accurate Formula Written (Formula Forge) +15 pts Accurate IUPAC Name Written (Formula Forge) +15 pts Imposter / False Match Callout (Unverified) -10 pts
Pro Strategy: Inspect the first element! If it is located left of the staircase on the periodic table (or is ammonium, NH₄⁺), it's Ionic. If both elements are to the right, it's Molecular!

Pair Formula IUPAC Name Bond Type Nomenclature & Structural Rationale #01 MgCl₂ Magnesium chloride Ionic Main group metal (Mg²⁺) + halogen (2 Cl⁻). Fixed charge; NO prefixes allowed. #02 CO₂ Carbon dioxide Molecular 2 nonmetals. Prefix mono- omitted on first element; di- required on oxide. #03 Fe₂O₃ Iron(III) oxide Ionic Transition metal. Anion charge (3 × -2 = -6) requires 2 Fe³⁺ (+6); Roman numeral (III). #04 N₂O Dinitrogen monoxide Molecular 2 nonmetals. Prefix di- on nitrogen; prefix mono- required on second element (oxide). #05 CuCl Copper(I) chloride Ionic 1:1 ratio with Cl⁻ (-1) dictates copper cation has +1 charge; Roman numeral (I). #06 SF₆ Sulfur hexafluoride Molecular 2 nonmetals. Single sulfur (no mono-); 6 fluorines take Greek prefix hexa-. #07 NH₄NO₃ Ammonium nitrate Ionic Crucial trap! Contains NO metals, but ionic because NH₄⁺ cation bonds to NO₃⁻ anion. #08 PCl₃ Phosphorus trichloride Molecular 2 nonmetals. Single phosphorus; 3 chlorines take prefix tri-. #09 PbSO₄ Lead(II) sulfate Ionic Sulfate ion is SO₄²⁻ (-2). Therefore lead cation must be Pb²⁺ (+2); Roman numeral (II). #10 N₂O₄ Dinitrogen tetroxide Molecular 2 nonmetals. Prefix di- (2) and tetra- (4); "a" in tetra is dropped before oxide. #11 Ca(OH)₂ Calcium hydroxide Ionic Ca²⁺ balances two OH⁻ polyatomic hydroxide ions. Fixed charge group 2 metal. #12 P₂O₅

Two NO₃⁻ (-2 total) requires Cu²⁺; Roman numeral (II).
2 nonmetals; di- (2) and pentoxide (penta- drops 'a').

3 Fe²⁺ (+6) balance 2 PO₄³⁻ (-6); parentheses mandatory.
4. Dichlorine heptoxideMolecular

5. Potassium carbonateIonic
Two K⁺ (+2) balance one CO₃²⁻ (-2).
6. Tetranitrogen tetrasulfideMolecular
tetra- N (4) + tetra- S (4). Do not reduce molecular!
4 Round 4: Imposter Alert Error Diagnoses Violation: Greek prefix "di-" was used on an ionic compound. Ca is an alkaline earth metal.
Correct: Calcium chloride
Violation: The Roman numeral (III) signifies the cation charge (Fe³⁺), not the number of iron atoms!
Violation: Both P and O are nonmetals (covalent bond). Greek prefixes are mandatory to show atom counts.
Correct: Diphosphorus trioxide
Teacher Facilitation Alert: Watch for students trying to reduce molecular formulas (e.g. reducing N₄S₄ to NS or N₂O₄ to NO₂). Remind them that unlike ionic empirical formulas, molecular formulas represent the actual physical molecule and must NEVER be simplified. Also remind students that Roman numerals indicate charge , not subscript quantity.
