CHEM 205 lecture 3
Cards (6)
- Ionic compoundsEnergy favourable interactions between ions
- Naming ionic compounds
- Contains metal or NH4+
- Cation: Ammonium, metal (use name of atom), or transition metal (roman numerals)
- Anion: monoatomic - add -ide at the end
- Anion: polyatomic - __ate, __ite (one less O than -ate), per__ate (one more O than -ate), hypo__ite (one less O than -ite)
- Naming molecular compounds
- Not containing an acid: using prefixes for cation (mono, di, tri, etc.), add -ide to the end of the anion
- Containing an acid: H + halogen - hydro___ic acid, H + polyatomic ion - __ate à __ic acid, __ite à __ous acid
- Coulomb's lawGoverns force of attraction
- Lattice energyEnergy released when separating one mole of an ionic compound into ions in the gas phase
