Which of the two cations `Mg^(2+)` and `Al^(3+)` is smaller?

Mg^(2+) and Al^(3+) have same

Which is the smallest among Na^(o+) , Mg^(2+) , Al^(3+) , and why?

The standard emf of the cell Mg|Mg^(2+)||Al^(3+)|Al is 0.71V at 298 K. Equilibrium constant of the reaction 3Mg^(2+)+2Al to 3Mg+2Al^(3+) is

(A) : Mg^(2+) and Al^(3+) are isolectronic but the magnitude of ionic radius of Al^(3+) is less than that in Mg^(2+) . (R ) : The effective nuclear charge on the outermost electrons in Al^(3+) is greater than that in Mg^(2+) .

Al^(3+) is smaller than Ca^(2+) .

Write the Lewis symbols of Mg and Al.

Write the Lewis symbols of Mg and Al.

Assertion (A) : The first ionization energy of Al is lower than Mg. Reason (R ) : Atomic radius of Al is smaller than Mg.
