Electron affinity of the atom is the energy released when:

Correct answer: B. Electron is added to gaseous atom.

  • A. Covalent bond of molecule is broken.
  • B. Electron is added to gaseous atom.
  • C. Electron is removed from gaseous atom.
  • D. Covalent bond is formed between the atoms.

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.
