Question

Which is smaller mg2+ or al3+?

Answer 1

Answer:

As the effective nuclear charge which holds the electron of a atom increases the radius of an atom decreases as it is tightly pulled towards the nucleus of atom. ... Therefore radius of Al3+ is less than Mg2+.

Answer 2

Answer:

Al3+ is smaller than Mg2+

Explanation:

As the effective nuclear charge which holds the electron of a atom increases the radius of an atom decreases as it is tightly pulled towards the nucleus of atom.Therefore radius of Al3+ is less than Mg2+.
