Question:
The correct order of metallic character of the following elements is
The correct order of metallic character of the following elements is
Show Hint
Across a period, atomic radius decreases and ionization energy increases, making metallic character decrease.
Updated On: Apr 24, 2026
- Na$>$Mg$>$Si$>$P
- Mg$>$Na$>$Si$>$P
- Na$>$Mg$>$P$>$Si
- Si$>$P$>$Mg$>$Na
- P$>$Si$>$Mg$>$Na
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Metallic character decreases across a period from left to right.
Step 2: Detailed Explanation:
Na, Mg, Si, and P are in Period 3. Na is an alkali metal (most metallic), Mg is an alkaline earth metal, Si is a metalloid, and P is a non-metal. So the order is Na$>$Mg$>$Si$>$P.
Step 3: Final Answer:
The correct order is Na$>$Mg$>$Si$>$P.
