Step 2:: Sodium (Na)
- Classification: $$\text{Sodium} \rightarrow \text{Metal}
- Sodium is located in Group 1 (alkali metals) of the periodic table - It has metallic properties: * Soft, silvery-white metal * Highly reactive * Conducts electricity
Step 3:: Potassium (K)
- Classification: $$\text{Potassium} \rightarrow \text{Metal}
- Potassium is also located in Group 1 (alkali metals) of the periodic table - Similar properties to sodium: * Soft, silvery-white metal * Highly reactive * Conducts electricity
Step 4:: Chlorine (Cl)
- Classification: $$\text{Chlorine} \rightarrow \text{Nonmetal}
- Chlorine is located in Group 17 (halogens) of the periodic table - It has nonmetallic properties: * Exists as a gas at room temperature * Poor conductor of electricity * Highly reactive, but in a different way from metals
Final Answer
- Sodium: Metal - Potassium: Metal - Chlorine: Nonmetal
