NEET 2026, Chemistry Q24: Periodicity In Atomic Properties
NEET2026Chemistry
Q.
The correct order of increasing metallic character of Na, Be, P, Mg and Si is :
- A
Be < Si < P < Mg < Na
- B
P < Si < Na < Mg < Be
- C
P < Si < Be < Mg < Na
- D
P < Mg < Be < Si < Na
Solution
Metallic character is inversely related to ionisation energy. The ionisation energies decrease as Na < Mg < Be < Si < P, so metallic character increases in the reverse direction:
P < Si < Be < Mg < Na.
