Question

1. which of the following are true for the compound cacl₂? select two correct answers. its name is calcium chloride. it forms an ionic bond. it forms a covalent bond. its name is calcium chlorite. it forms a metallic bond.

Explanation:

Step1: Analyze the compound name

Calcium chloride is \(CaCl_{2}\), while calcium chlorite would be \(Ca(ClO_{2})_{2}\). So "Its name is calcium chloride" is correct and "Its name is calcium chlorite" is wrong.

Step2: Analyze the bond type

Calcium (\(Ca\)) is a metal (from Group 2 of the periodic table) and chlorine (\(Cl\)) is a non - metal (from Group 17). Ionic bonds form between metals and non - metals. Covalent bonds form between non - metals and metallic bonds form between metals. So "It forms an ionic bond" is correct, "It forms a covalent bond" and "It forms a metallic bond" are wrong.

Answer:

• Its name is calcium chloride.
• It forms an ionic bond.
