For isoelectronic ions, how are effective nuclear charge and ionic radius related?

A) As nuclear charge (Z) increases, ionic radius increases.

B) As nuclear charge (Z) increases, ionic radius decreases.

Respuesta :

For isoelectronic ions, as nuclear charge increases, effective nuclear charge increases and ionic radius decreases.

Answer:

Therefore, correct option is B.

Explanation:

For isoelectronic ions : As the nuclear charge increases the atomic radius decreases due to increase in the attractive force on the outermost electrons.
