Question

arrange these ions in the increasing order of their size and give reason for your answer. Al3+ , Na+, Mg2+, O2-, F-​

Answer 1

Step-by-step explanation:

As all ions have same number of electrons but they have different amount of nuclear charge . So, positive ions have more nuclear charge,, because of more number of protons ,,than negative ions. Due to more nuclear charge electrons get strongly attracted toward nucleus. As result , they are smaller in size than negative ions.
