Completed chemistry worksheet showing the step-by-step process for determining ionic formulas and names.

- The chemical formulas in the first table are mostly correct, but there are several errors in the metal ion charges and compound names.
- For barium and chlorine: The metal ion is Ba²⁺ (not Ba²⁺⁺), the non-metal ion is Cl⁻, the formula is BaCl₂, and the name is Barium Chloride.
- For sodium and oxygen: The metal ion is Na⁺, the non-metal ion is O²⁻, the formula is Na₂O, and the name is Sodium Oxide.
- For aluminum and nitrogen: The metal ion is Al³⁺, the non-metal ion is N³⁻, the formula is AlN, and the name is Aluminum Nitride.
- For lithium and sulfur: The metal ion is Li⁺, the non-metal ion is S²⁻, the formula is Li₂S, and the name is Lithium Sulfide.
- For magnesium and oxygen: The metal ion is Mg²⁺, the non-metal ion is O²⁻, the formula is MgO, and the name is Magnesium Oxide.
- For calcium and chlorine: The metal ion is Ca²⁺, the non-metal ion is Cl⁻, the formula is CaCl₂, and the name is Calcium Chloride.
- For boron and chlorine: Boron is a metalloid, not a metal, and typically forms covalent compounds. The common compound is BCl₃ (Boron Trichloride), not an ionic compound with B³⁺.
- For beryllium and sulfur: The metal ion is Be²⁺, the non-metal ion is S²⁻, the formula is BeS, and the name is Beryllium Sulfide.
- In the second table, most formulas are correct, but some need correction for charge balance:
- Be²⁺ with O²⁻ should be BeO (correct).
- Be²⁺ with S²⁻ should be BeS (correct).
- Be²⁺ with N³⁻ should be Be₃N₂ (not Be₃S₂ as written).
- Be²⁺ with P³⁻ should be Be₃P₂ (correct).
- Mg²⁺ with O²⁻ should be MgO (correct).
- Mg²⁺ with S²⁻ should be MgS (correct).
- Mg²⁺ with N³⁻ should be Mg₃N₂ (correct).
- Mg²⁺ with P³⁻ should be Mg₃P₂ (correct).
- Ca²⁺ with O²⁻ should be CaO (correct).
- Ca²⁺ with S²⁻ should be CaS (correct).
- Ca²⁺ with N³⁻ should be Ca₃N₂ (correct).
- Ca²⁺ with P³⁻ should be Ca₃P₂ (correct).
- Al³⁺ with O²⁻ should be Al₂O₃ (correct).
- Al³⁺ with S²⁻ should be Al₂S₃ (correct).
- Al³⁺ with N³⁻ should be AlN (not AlN as written, which is correct for 1:1 ratio, but the charge balance requires AlN for Al³⁺ and N³⁻).
- Al³⁺ with P³⁻ should be AlP (correct).
- Ga³⁺ with O²⁻ should be Ga₂O₃ (correct).
- Ga³⁺ with S²⁻ should be Ga₂S₃ (correct).
- Ga³⁺ with N³⁻ should be GaN (correct).
- Ga³⁺ with P³⁻ should be GaP (correct).
- B³⁺ with F⁻ should be BF₃ (correct).
- B³⁺ with Cl⁻ should be BCl₃ (correct).
- B³⁺ with O²⁻ should be B₂O₃ (correct).
- B³⁺ with S²⁻ should be B₂S₃ (correct).
- B³⁺ with N³⁻ should be BN (correct).
- B³⁺ with P³⁻ should be BP (correct).
