Periodic Classification and Periodic Properties 2 Question 45
45. Arrange the following as stated :
“Increasing order of ionic size” $\mathrm{N}^{3-}, \mathrm{Na}^{+}, \mathrm{F}^{-}, \mathrm{O}^{2-}, \mathrm{Mg}^{2+}$
(1991, 1M)
Show Answer
Solution:
- Ionic size $\mathrm{Mg}^{2+}<\mathrm{Na}^{+}<\mathrm{F}^{-}<\mathrm{O}^{2-}<\mathrm{N}^{3-}$
Already explained in question 1 (i).
