Question

The size of isoelectronic species $F$, Ne and $N{a}^{+}$ is affected by

• A. nuclear charge $(Z)$
• B. valence principal quantum no. $(n)$
• C. electron-electron interaction in the outer orbitals
• D. none of the factors because their size is same.

Answer 1

Answer: (A)

The size of isoelectronic species depends upon effective nuclear charge and decreases with increase in effective nuclear charge.
