Given below are two statements :
Statement (I): The metallic radius of Al is less than that of Ga.
Statement (II) : The ionic radius of (\mathrm{Al}^{3+}) is less than that of (\mathrm{Ga}^{3+}).
In the light of the above statements, choose the most appropriate answer from the options given below :
Statement (I): The metallic radius of Al is less than that of Ga.
Statement (II) : The ionic radius of (\mathrm{Al}^{3+}) is less than that of (\mathrm{Ga}^{3+}).
In the light of the above statements, choose the most appropriate answer from the options given below :
Options
- ABoth Statement I and Statement II are incorrect
- BStatement I is incorrect but Statement II is correct
- CStatement I is correct but Statement II is incorrect
- DBoth Statement I and Statement II are correct
Correct answer
B. Statement I is incorrect but Statement II is correct
Step-by-step solution
(\Rightarrow) The metallic radius order of (~\&~ ) is
()
(due to poor shielding of d-subshell electrons)
(\Rightarrow) The ionic radius order of (~\&~ ) is (\mathrm{B}^{+3} \lt )
