**25.** Arrange each set in order of increasing radius, and explain the basis for this order.(a) Al, B, K, Mg, Ar(b) P, Br⁻, Cl, Kr---### ExplanationFor each set:- **Set (a):** Consider the periodic trends in atomic radii, such as moving across a period from left to right, which decreases the radius due to increased effective nuclear charge. Moving down a group increases the radius as additional electron shells are added.- **Set (b):** Note the effect of negative ions (anions) on atomic size. Anions are typically larger than the neutral atoms from which they are derived due to electron-electron repulsion in the additional electron.In both cases, it’s essential to apply the concepts of periodic trends and ionization changes to explain the order of increasing radius.

The ionisation energy generally increases across a period. However, there are two exceptions to the otherwise smooth increase in the first ionisation energy across periods. In Periods 2 and 3, there are dips at the Group 3A (13) elements, boron and aluminium, and at the Group 6A (16) elements, oxygen and sulfur. Explain this trend using suitable examples.
explain the method of ranking increasing radius as well.
