Vedclass · Answer

(A) Electronegativity is the tendency of an atom to attract a shared pair of electrons towards itself.In the periodic table,electronegativity generally decreases down a group as the atomic size increases and the effective nuclear charge decreases.All the given elements ($Li$,$Na$,$K$,$Rb$) belong to Group $1$ (alkali metals).Since $Li$ is at the top of the group,it has the smallest atomic size and the highest effective nuclear charge among the given options.Therefore,$Li$ has the highest electronegativity.

Keeping in view the periodic law and the periodic table,suggest which of the following elements should have the maximum electronegative character.

Among the following,the pairs of elements having approximately the same electronegativity values are:
$I$. $H$ and $P$
$II$. $Be$ and $Al$
$III$. $N$ and $Cl$
$IV$. $C$ and $P$

The $EN$ (Electronegativity) of element $A$ is $E_1$ and its $IP$ (Ionization Potential) is $E_2$. Hence,the $EA$ (Electron Affinity) will be:
