The correct Answer is:
To solve the question regarding the effect of the formation of interstitial compounds on transition metals, we will follow these steps: ### Step 1: Define Transition Metals Transition metals are defined as elements that have partially filled d orbitals. They are found in groups 3 to 12 of the periodic table. **Hint:** Remember that transition metals are characterized by their d orbitals and their position in the periodic table. ### Step 2: Understand Interstitial Compounds Interstitial compounds are formed when small non-metallic atoms (such as carbon, nitrogen, or oxygen) occupy the interstitial spaces (the gaps) between the metal atoms in a metal lattice. **Hint:** Think about what happens when small atoms fit into the spaces between larger atoms in a metal structure. ### Step 3: Analyze the Effect of Interstitial Compounds The presence of these small non-metallic atoms leads to the formation of covalent bonds with the transition metal atoms. This bonding increases the overall strength of the material. **Hint:** Consider how the addition of small atoms can affect the overall structure and properties of the metal. ### Step 4: Determine the Impact on Hardness The formation of interstitial compounds typically makes transition metals harder. This is because the covalent bonds formed with the non-metallic atoms increase the rigidity of the metal structure. **Hint:** Focus on the relationship between bonding and material hardness. ### Step 5: Evaluate the Options Given the options: 1. More soft 2. More ductile 3. More metallic 4. More hard Since we have established that the formation of interstitial compounds makes transition metals harder, the correct answer is option 4: "more hard." **Hint:** Cross-check each option with the information gathered about interstitial compounds and their effects on transition metals. ### Final Answer The formation of interstitial compounds makes the transition metal **more hard**.
