MCQ
Which of the following statements is correct
- ✓${X^ - }$ ion is larger in size than $X$ atom
- B${X^ + }$ ion is larger in size than $X$ atom
- C${X^ + }$ ion is larger in size than ${X^ - }$ ion
- D${X^ + }$ and ${X^ - }$ ions are equal in size
✓
Answer
Correct option: A.
${X^ - }$ ion is larger in size than $X$ atom
a
(a)${X^ - }$ ion larger in size than $X$ atoms. Because of low effective nuclear charge on ${X^ - }$ has a bigger size.
