Answer
Explanation:
Step1: Naming ionic compounds rule
The name of an ionic compound starts with the name of the metal (cation) followed by the name of the non - metal (anion). The anion name usually ends in “-ide”.
Step2: Naming NaBr
The metal is sodium (Na) and the non - metal is bromine (Br). So the name is sodium bromide.
Step3: Naming LiF
The metal is lithium (Li) and the non - metal is fluorine (F). So the name is lithium fluoride.
Step4: Naming MgBr₂
The metal is magnesium (Mg) and the non - metal is bromine (Br). So the name is magnesium bromide.
Step5: Naming AlI₃
The metal is aluminum (Al) and the non - metal is iodine (I). So the name is aluminum iodide.
Step6: Naming K₂S
The metal is potassium (K) and the non - metal is sulfur (S). So the name is potassium sulfide.
Step7: Writing formula for cesium fluoride
Cesium has a charge of + 1 (Cs⁺) and fluoride has a charge of - 1 (F⁻). The formula is CsF.
Step8: Writing formula for strontium chloride
Strontium has a charge of + 2 (Sr²⁺) and chloride has a charge of - 1 (Cl⁻). To balance the charges, we need 2 chloride ions. The formula is SrCl₂.
Step9: Writing formula for barium oxide
Barium has a charge of + 2 (Ba²⁺) and oxide has a charge of - 2 (O²⁻). The formula is BaO.
Step10: Writing formula for potassium phosphide
Potassium has a charge of + 1 (K⁺) and phosphide has a charge of - 3 (P³⁻). To balance the charges, we need 3 potassium ions. The formula is K₃P.
Step11: Writing formula for aluminum nitride
Aluminum has a charge of + 3 (Al³⁺) and nitride has a charge of - 3 (N³⁻). The formula is AlN.
Answer:
- Ionic compounds are named by writing the name of the metal (cation) first and then the name of the non - metal (anion) with the anion name ending in “-ide”.
