Question
Identify the wrong statement in the following.
Options
A.Amongst iso electronic species, smaller the positive charge on the cation, smaller is the ionic radius
B.Amongst iso electronic species, greater the negative charge on the anion, larger is the ionic radius
C.Atomic radius of the elements increases as one moves down the first group of the Periodic Table
D.Atomic radius of the elements increases as one moves across from left to right in the 2nd period of the Periodic Table
Solution
Atomic radius of the elements decreases across a period from left to right due to increase in effective nuclear charge. On moving down a group, since, number of shells increases, so atomic radius increases.
Amongst iso electronic species, ionic radius increases with increase in negative charge or decrease in positive charge.
Amongst iso electronic species, ionic radius increases with increase in negative charge or decrease in positive charge.
