Electron affinity of the atom is the energy released when:
Correct answer: A. Electron is added to gaseous atom.
- A. Electron is added to gaseous atom.
- B. Covalent bond is of molecule is broken.
- C. Electron is removed from gaseous atom.
- D. Covalent bond is formed between the atoms.
Explanation
The electron affinity of an atom is the energy released when an electron adds to an empty or partially filled orbital of an isolated gaseous atom in its valence energy level to form an anion having a unit negative charge.

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.
