Interpretation:

The change in ionic radius needs to be related with change in ion formation across the periodic table.

Concept introduction:

Atomic radius is used for distance between the nucleus and outermost shell of electrons of the atomic and ionic particle.

Expert Solution & Answer

Answer to Problem 14STP

A cation is smaller than its original atom because cation lost electrons from its outermost shell.

Explanation of Solution

In a period from left to right, an atomic radius decreases. A cation is smaller than its original atom because atom lost electrons from its outermost shell. In this case, nucleus pulls electron cloud closer to it self. But an anion is bigger than its original atom because anions gain electrons which are added to its outermost shell.

Conclusion

Cation lost electrons from its outermost shell. Thus a cation is smaller than its original atom. In this case nucleus pulls electron cloud closer to it self.
