Key Concepts
These are the key concepts you need to understand to accurately answer the question.
Chemical Formulas
Ionic Bonding
Cation and Anion Pairing
- Cations are positively charged ions, typically formed from metals. Examples include \text{Li}^+ and \text{Cu}^{2+}.
- Anions are negatively charged ions, typically formed from non-metals. Examples include \text{NO}_2^{-} and \text{CO}_3^{2-}.
Neutral Compounds
- Identify the charges of each ion.
- Determine how many of each ion are needed to balance the charges.
- Write the formula with the appropriate subscripts to show these quantities.
