Step 1:I'll solve this problem step by step:
Step 2:: Identify the Element's Properties
Cobalt (Co) is a chemical element located in the periodic table with atomic number 27. To determine its classification, we need to examine its fundamental characteristics.
Step 3:: Analyze Metallic Properties
- Cobalt is a hard, lustrous, silver-gray metal - It has typical metallic properties such as: * High electrical conductivity * High thermal conductivity * Malleable and ductile * Solid at room temperature * Capable of forming positive ions
Step 4:: Periodic Table Location
Cobalt is located in: - Group 9 - Period 4 - Transition metal block
Step 5:: Classification Determination
Based on its properties and location in the periodic table, Cobalt is definitively a METAL.
Final Answer
Metal Key Reasoning: - Metallic physical properties - Located in transition metal block - Conducts electricity and heat - Can form positive ions - Lustrous appearance - Malleable and ductile structure
