Identify each compound by bond type (ionic or covalent)

CaCl2 NO5 MgSO4 Cu2S3 P2O5

1 answer

Here’s the classification of each compound by bond type:

  1. CaCl2 (Calcium chloride) - Ionic bond

    • This compound consists of calcium ions (Ca²⁺) and chloride ions (Cl⁻), which form an ionic bond.
  2. NO5 (Nitrogen pentoxide) - Covalent bond

    • Nitrogen pentoxide contains nitrogen and oxygen that share electrons, forming covalent bonds.
  3. MgSO4 (Magnesium sulfate) - Ionic bond

    • Magnesium sulfate consists of magnesium ions (Mg²⁺) and sulfate ions (SO₄²⁻), indicating an ionic bond.
  4. Cu2S3 (Copper(III) sulfide) - Ionic bond

    • In this case, copper (Cu) forms ionic bonds with sulfide ions (S²⁻) to create the compound.
  5. P2O5 (Diphosphorus pentoxide) - Covalent bond

    • This compound is formed by sharing electrons between phosphorus and oxygen atoms, indicating covalent bonds.

To summarize:

  • Ionic Compounds: CaCl2, MgSO4, Cu2S3
  • Covalent Compounds: NO5, P2O5
