Vedclass · Answer

(B) $(i)$ First ionisation enthalpy of $He$ $(2372 \ kJ/mol)$ is less than the second ionisation enthalpy of $Li$ $(7298 \ kJ/mol)$. This is correct.
$(ii)$ $Li$ has the highest second ionisation enthalpy because removing the second electron from $Li^+$ requires breaking the stable $1s^2$ noble gas configuration. This is correct.
$(iii)$ All transition elements are $d$-block elements,but all $d$-block elements are not transition elements (e.g.,$Zn, Cd, Hg$). This is incorrect.
$(iv)$ The letter '$J$' is the only alphabet not found in the periodic table. This is correct.
$(v)$ Francium is extremely rare,and its concentration in the Earth's crust is estimated to be $\sim 10^{-18} \ ppm$. This is correct.
Therefore,statements $(i), (ii), (iv),$ and $(v)$ are correct.

List-$A$	List-$B$
$(1)$ $He$	$(A)$ High electron gain enthalpy
$(2)$ $Cl$	$(B)$ Electropositive element
$(3)$ $Ca$	$(C)$ Strong reducing agent
$(4)$ $Li$	$(D)$ High ionization enthalpy
