F−,O2− and N3− all are isoelectronic species in which N3− have least number of protons due to which it's size increases as least nuclear attraction
is experienced by the outer shell electrons. Size order N3−>O2−>F−
The ionic radii of F− and O2− respectively are 1.33 A and 1.4A, while the covalent radius of N is 0.74A
The correct statement for the ionic radius of N3− from the following is :
Held on 25 Jul 2021 · Verified 6 Jul 2026.
It is smaller than F− and N
It is bigger than O2− and F−
It is bigger than F− and N, but smaller than of O2−
It is smaller than O2− and F−, but bigger than of
N

First and second ionization enthalpies of lithium are $520$ kJ mol$^{-1}$ and $7297$ kJ mol$^{-1}$ respectively. Energy required to convert $3.5$ mg lithium (g) into $\text{Li}^{2+}$(g) $[\text{Li(g)} \rightarrow \text{Li}^{2+}\text{(g)}]$ is _______ kJ mol$^{-1}$. (nearest integer) [Molar mass of Li $= 7$ g mol$^{-1}$]
