QUESTION: 14

The atomic radius of elements of which of these would be nearly same

Solution:

The atomic radii of the d- block elements of a given series decrease with increase in atomic number but this decrease becomes small after midway. The decrease in atomic radii in the beginning, is due to an increase in nuclear charge from member to member which tends to reduce the size. At the same time, the addition of extra electrons to (n-1)d orbitals also provides the screening effect. As the number of d-electrons increases, the screening effect increases. Thus, there are operating two effects namely screening effect and nuclear charge effect which oppose each other. In the midway onwards of the series both these effects become nearly equal and thus, there is no change in atomic radii inspite of the fact that atomic number increases gradually.

Solution:
QUESTION: 36
The highest electronegative element is
Solution: The electronegativity values for the elements decrease down a group. This is because as we move down the group atomic radius as well as screening effect increases. Thus, the force of attraction with which the nucleus pulls the valence electrons towards itself decreases and consequently the electronegativity values also decrease. The electronegativity values for alkali metals follows the order:
Li > Na > K > Rb.
