The Ionic radii appeared to be a/an _ property.
Correct answer: C. Additive
- A. Associative
- B. Multiplicative
- C. Additive
- D. All of these
Explanation
The ionic radii appear to be an additive property because an ion's size is primarily determined by the number of electrons in its outermost energy level, and the addition or removal of electrons from an atom can result in the formation of new ions with different radii. When atoms combine to form an ionic compound, the resulting ion's size will be determined by the sum of the sizes of the individual ions. This means that the size of an ionic compound can be predicted based on the size of its constituent ions.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
