Atomic radii decrease across the period. Cations are smaller than their parent atoms. Among these isoelectronic ions, the one with larger positive nuclear charge will have the smaller radius. So, here the largest atom is Mg and the smallest one is Al3+.

Arrange the following atoms and ions in the increasing order of atomic...
The order of atomic size can be determined by comparing the number of protons in the nucleus and the number of electron shells.
Mg: 12 protons, 3 electron shells
Mg2+: 12 protons, 2 electron shells (loss of 2 electrons)
Al: 13 protons, 3 electron shells
Al3+: 13 protons, 2 electron shells (loss of 3 electrons)
Based on this information, the increasing order of atomic size is:
Mg2+ < al3+="" />< mg="" />< al="" />
Mg: 12 protons, 3 electron shells
Mg2+: 12 protons, 2 electron shells (loss of 2 electrons)
Al: 13 protons, 3 electron shells
Al3+: 13 protons, 2 electron shells (loss of 3 electrons)
Based on this information, the increasing order of atomic size is:
Mg2+ < al3+="" />< mg="" />< al="" />
