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:

  1. 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”.
