The radius of `Na^(+)` cation is less than that of Na atom. Give reason.

The radius of Na^(23) nucleus is

Radius of cation is less than that of parental atom, but radius of anion is greater than that of parental atom. Explain.

Why is Na^(+) cation smaller than the parent atom Na ?

The atomic radius of Ga is less than that of Al - Why ?

The ionic radius of Na^(+) is less than the atomic radius of Na but the ionic radius of Cl^(-) is greater than the atomic radius of Cl-why?

Atomic radius of Ga is slightly less than that of Al. The reason is-

Why the atomic radius of gallium is less than that of Al?

Assertion: Na^(+) and Al^(3+) are isoelectronic but the magnitude of the ionic radius of Al^(3+) is less than that of Na^(+) Reason: The magnitude of effective nuclear charge of the outer shell electrons in Al^(3+) is greater than in Na^(+)
