Question:

In case of isoelectronic species the size of F , Ne and Na+ is affected by:

Updated On: Mar 21, 2025
  • Principal quantum number (n)
  • None of the factors because their size is the same
  • Electron-electron interaction in the outer orbitals
  • Nuclear charge (z)

The Correct Option is D

Solution and Explanation

In F \text{F}^- , Ne, and Na+ \text{Na}^+ , all have 1s2,2s2,2p6 1s^2, 2s^2, 2p^6 configuration. They differ in size due to differences in nuclear charge, affecting their pull on electrons.
