1.	Assertion : In case of isoelectronic ions the ionic size increases with the increase in atomic number. Reason: The greater the attraction of nucleus , greater is the ionic radius.
Answer» If both assertion and REASON are true and the reason is the correct EXPLANATION of the assertion If both assertion and reason are true butreason isnot the correct explanation of the assertion If assertion is true but reason is false If the assertion and reason both are false Solution :Both assertion and reason are false. In case of isoelectronic , i.e., ions, having the same number of electrons and different NUCLEAR charge, the size decreases with increase in ATOMIC NUMBERS.
