MCQ
Which will show maximum non-metallic character
- ✓$B$
- B$Be$
- C$Mg$
- D$Al$
✓
Answer
Correct option: A.
$B$
a
Non-metallic character decreases as we move down the group and across a period non-metallic character increases from left to right.
Non-metallic character decreases as we move down the group and across a period non-metallic character increases from left to right.
So here $B$ will show maximum non-metallic character.
