Step 1:I'll solve this problem by following the systematic approach of identifying chlorine's chemical properties.
Step 2:: Locate Chlorine on the Periodic Table
- Chlorine is located in Group 17 (the halogen group) on the periodic table - It is found in Period 3
Step 3:: Analyze Chemical Properties
* Exist as diatomic molecules ($$Cl_{2}$$)
- Halogens are characterized by: * High electronegativity * Typically form negative ions * Non-metallic chemical behavior
Step 4:: Evaluate Physical Properties
- Chlorine is: * A green-yellow gas at room temperature * Poor conductor of electricity * Cannot be drawn into wires * Brittle and non-lustrous
Step 5:: Determine Classification
- Based on its location and properties, chlorine exhibits classic nonmetal characteristics
Final Answer
The key characteristics that identify chlorine as a nonmetal are its position in the halogen group, its gaseous state at room temperature, low electrical conductivity, and tendency to form negative ions during chemical reactions.
