Which of the following statement is correct for `CsBr_(3)`

Options

A. It is a covalent compound
B. It contains `Cs^(3+)` and `Br^(-)` ions
C. It contains `Cs^(+)` and `Br_(3)^(-)` ions
D. It contain `Cs^(+),Br^(-)` and lattice, `Br_(2)` molecule.

Explanation

To determine the correct statement regarding CsBr₃, we need to analyze its structure and composition step by step.

### Step 1: Identify the nature of CsBr₃
CsBr₃ is a compound formed from cesium (Cs) and bromine (Br). Cesium is an alkali metal, and bromine is a halogen. Alkali metals typically form ionic compounds with halogens.

**Hint:** Remember that ionic compounds are formed between metals and non-metals, where metals lose electrons and non-metals gain them.

### Step 2: Determine the oxidation states
In CsBr₃, cesium (Cs) has an oxidation state of +1, while bromine (Br) can have multiple oxidation states, but in this case, it is -1. The formula indicates that there are three bromine atoms for each cesium atom.

**Hint:** Check the common oxidation states of the elements involved to understand how they combine.

### Step 3: Identify the ions present
Based on the oxidation states, we can deduce that CsBr₃ consists of one cesium ion (Cs⁺) and three bromide ions (Br⁻). Therefore, the correct representation of the ions in CsBr₃ is:
- Cation: Cs⁺
- Anion: 3Br⁻

**Hint:** Ionic compounds are made up of cations and anions, so identify them correctly.

### Step 4: Analyze the statements
Now, we need to evaluate the statements given in the question regarding CsBr₃:
1. CsBr₃ is a covalent compound. (Incorrect)
2. CsBr₃ contains Cs³⁺. (Incorrect)
3. CsBr₃ contains Cs⁺ and Br⁻. (Correct)
4. CsBr₃ contains Cs⁺ and Br₃⁻. (Incorrect)

From our analysis, the only correct statement is that CsBr₃ contains Cs⁺ and Br⁻.

**Hint:** Cross-check each statement with the information derived from the compound's composition.

### Conclusion
The correct statement for CsBr₃ is that it contains Cs⁺ and Br⁻ ions.
