Consider the following order:
size
electronegativity
metallic character
number of unpaired electrons
More than one of the above properties (a—d) shows the correct trend.
Interpretation:
Among the given properties, the one that indicates the order which shows the correct trend is to be identified.
Concept Introduction:
The ability that is possessed by an atom to attract the bonding pair of electrons towards itself is known as electronegativity. The electronegativity decreases while going down the group and increases while from moving left to right in the period.
The distance between the nucleus and the valence shell electrons of an atom is known to be the atomic size of that atom. According to the periodic table, the atomic size increases while going down the group and decreases while moving from left to right in the period.
Reason for correct option:
(b) The given order is,
This order follows the electronegativity trend. According to the periodic table, the electronegativity of the elements increases while moving from left to right in the period
