NEETChemistryPeriodic Table and PeriodicityMCQ+4 / −1
Identify the wrong statement in the following.
- AAmongst isoelectronic species, smaller the positive charge on the cation, smaller is the ionic radius.
- BAmongst isoelectronic species, greater the negative charge on the anion, larger is the ionic radius.
- CAtomic radius of the elements increases as one moves down the first group of the periodic table.
- DAtomic radius of the elements decreases as one moves across from left to right in the 2nd period of the periodic table.

Correct answer: A
When positive charge on the cation increases, effective nuclear charge increases. Thus atomic size decreases.
