The ionic radius of an ion is the radius of the ion while considering it to be_in shape.
Correct answer: D. Spherical
- A. Oval
- B. Round
- C. Rectangular
- D. Spherical
Explanation
The ionic radius of an ion is the radius of the ion when it is considered to be a sphere. It represents the distance from the nucleus to the outermost electron in the ion, assuming the electron distribution is spherically symmetric. This concept allows for easy comparison of ion sizes, and it is widely used in chemistry and crystallography to describe the size of ions in various compounds.

About Shape of Ionic Crystals
Ionic crystal shape depends on the regular arrangement of oppositely charged ions in a three-dimensional lattice. The topic covers coordination number, radius ratios, lattice geometry and structures such as sodium chloride, caesium chloride and zinc sulfide, which should not be confused with the molecular shapes predicted by VSEPR theory.
