Question

explain the following (1) radius of cation is lesser than that of the the atom (2)radius of anion is more than that of the atom (3)In isoelectronic ions radii decrease with increase in atomic number​

Answer 1

Explanation:

1. Because they have lesser electrons

2. Anions are formed by the gain of electrons

3. When we consider effective nuclear charge then, the ions of greater nuclear charge attract those ten electrons more strongly and pull them in more tightly. Therefore, the radii of the ions in an isoelectronic series decrease as nuclear charge

hope it will help u!
