A radius greater than its parent atom is called:
Correct answer: D. Anionic radii
- A. Cationic radii
- B. Atomic radii
- C. Covalent radii
- D. Anionic radii
Explanation
Cationic radii: Is smaller than the actual atom because of the loss of 1 electron from the parent atom Atomic radii: The actual radii of the parent atom Covalent radii: The covalent radius is a measure of the size of an atom that forms part of one covalent bond. Anionic radii: Is greater in size than the parent atom because when an atom gains an electron, the size of the electronic cloud increases

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.
