Radius of Ga is less than Al because of

Question

Radius of Ga is less than Al because of (A) lanthenoid contraction (B) greater screening effect (C) inert pair effect (D) none of the above

Tardigrade Admin · Accepted Answer

The atomic radius of Al=143 r/pm is 135 r/pm . The radius of Ga is less than Al due to greater screening effect in Al (It has 8 electrons in the penultimate shell).

Q. Radius of $G a$ is less than $A l$ because of

lanthenoid contraction

greater screening effect

inert pair effect

none of the above

The atomic radius of $A l = 143 r / p m$ is $135 r / p m$ . The radius of $G a$ is less than $A l$ due to greater screening effect in $A l$ (It has $8$ electrons in the penultimate shell).
