Study Notes
Lead Compounds
- Lead(II) ion is represented as PbO.
Naming Compounds
- All binary compounds, whether ionic or molecular, end with the suffix -ide.
Transition Metals
- Transition metals that exhibit multiple common charges are denoted by Roman numerals following their name.
Molecular Compounds
- Typically consist of two or more nonmetal elements.
Polyatomic Ions
- Chromate: CrO₄²⁻; Dichromate: Cr₂O₇²⁻.
Nonmetal Ions
