Question

The correct order or radii of three species Ca, Ca⁺ and Ca²⁺ is: 

Ca⁺>Ca²⁺>Ca

Ca⁺>Ca>Ca²⁺

Ca> Ca⁺> Ca²⁺

Ca²⁺>Ca⁺>Ca​

Answer 1

Answer:

Correct Answer:

S²⁻ > Cl⁻ >K⁺ >Ca²⁺

Explanation:

Among the isoelectronic species, size increases with the increase in negative charge. Thus S has the highest negative charge and hence largest in size followed by Cl, K and Ca.
