Classification Of Elements And Periodicity In Properties Question 1
Question 1 - 2024 (01 Feb Shift 1)
In case of isoelectronic species the size of $F^{-}, Ne$ and $Na^{+}$ is affected by:
(1) Principal quantum number (n)
(2) None of the factors because their size is the same
(3) Electron-electron interaction in the outer orbitals
(4) Nuclear charge (z)
Show Answer
Answer (4)
Solution
In $F^{-}, Ne, Na^{+}$ all have $1 s^{2}, 2 s^{2}, 2 p^{6}$ configuration. They have different size due to the difference in nuclear charge.
