Question

Ionic radii of
(a) Ti⁴⁺ < Mn²⁺ (b) ³⁵Cl⁻ < ³⁷Cl⁻
(c) K⁺ > Cl⁻¹ (d) P³⁺ > P⁵⁺

Answer 1

Answer:

Ionic radii of

(a) Ti⁴⁺ < Mn²⁺

(b) ³⁵Cl⁻ < ³⁷Cl⁻✔✔✌

(c) K⁺ > Cl⁻¹

(d) P³⁺ > P⁵⁺

Answer 2

Comparison of Ionic radii of ions

Explanation:

Ionic radii

It is defined as distance from the center of nuclei to outermost shell of a ion .

Please note

It is seen that "More is the positive charge on atom ,smaller is its size "

"More is the negative charge on  atom , bigger is its size ".

In the above question :

(a) Ti⁴⁺ < Mn²⁺ - This is false .

(b) ³⁵Cl⁻ < ³⁷Cl⁻  This is true

(c) K⁺ > Cl⁻¹ This is false

(d) P³⁺ > P⁵⁺ This is true
