Elements having atomic numbers $33, 47, 53, 59, 68, 74, 82$ are present in which blocks of the periodic table?

In a period, the first ionisation enthalpy of the element at the extreme left and the negative electron gain enthalpy of the extreme right element, except noble gases, are respectively.

In which of the following arrangements is the order $NOT$ according to the property indicated against it?

Assign true $(T)$ and false $(F)$ for the following statements and select the correct option for your answer:
$(a) \, IP$ of $O_{(g)}$ is less than $IP$ of $O_{(g)}^{-}$
$(b) \, IP$ of $Ne_{(g)}$ is greater than $IP$ of $Ne_{(g)}^{+}$
$(c) \, EA$ of $O_{(g)}^{+}$ is greater than $EA$ of $O_{(g)}$
$(d) \, IP$ of $N_{(g)}$ is greater than $IP$ of $N_{(g)}^{+}$

In which of the following sets,elements are not correctly arranged with the property shown in brackets?

Match the items in List-$A$ with the items in List-$B$.

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
