JEE Mains · Chemistry · STD 11 - 3. Classification of elements and periodicity in properties
Given below are two statements :
Statement I : \( K > Mg > Al > B \) is the correct order in terms of metallic character.
Statement II : Atomic radius is always greater than the ionic radius for any element.
In the light of the above statements, choose the correct answer from the options given below
- A Both Statement I and Statement II are true
- B Both Statement I and Statement II are false
- C Statement I is false but Statement II is true
- D Statement I is true but Statement II is false
Answer & Solution
Correct Answer
(D) Statement I is true but Statement II is false
Step-by-step Solution
Detailed explanation
Metallic character of s-block elements is greater than p-block elements. Anionic radius is greater than atomic radius but cationic radius is always less than atomic radius for any element.
