Answer

Let's break down the problem step-by-step to determine which statements about or models of ionic compounds are true.### Step 1: Understanding the Nature of Ionic CompoundsIonic compounds are composed of positive and negative ions held together by strong electrostatic forces in a crystal lattice structure. These ions are arranged in a repeating pattern that extends in all directions.### Step 2: Evaluating the StatementsLet's evaluate each statement given about or models of ionic compounds:1. **They DON'T show the nature of MOVEMENT of ions**: - **Explanation**: In a solid ionic compound, ions are fixed in place within the crystal lattice and do not move freely. However, in a liquid state or in solution, ions can move. or models typically represent the solid state and do not depict the movement of ions. - **Conclusion**: This statement is true.2. **They DON'T show the RELATIVE SIZES or SCALE of ions**: - **Explanation**: or models often simplify the representation of ions and may not accurately depict the relative sizes or scale of the ions. These models focus on the arrangement rather than the exact proportions. - **Conclusion**: This statement is true.3. **They DON'T show the INTERACTION of ions**: - **Explanation**: or models do show the interactions between ions in terms of their positions in the lattice and the electrostatic forces holding them together. These models are designed to represent how ions interact in the structure. - **Conclusion**: This statement is false.4. **[ALL of these]**: - **Explanation**: This option suggests that all the previous statements are true. - **Conclusion**: Since the third statement is false, this option is also false.### Step 3: Highlighting the Accurate AnswerBased on the evaluation, the true statements are:- They DON'T show the nature of MOVEMENT of ions.- They DON'T show the RELATIVE SIZES or SCALE of ions.Therefore, the accurate answer is:**They DON'T show the nature of MOVEMENT of ions****They DON'T show the RELATIVE SIZES or SCALE of ions**
