The minimum amount of energy required to remove an electron from its gaseous atom to form an ion is known as:
Correct answer: B. Ionization energy
- A. Electron affinity
- B. Ionization energy
- C. Electronegativity
- D. Potential energy
Explanation
OPTION A: Electron affinity is the energy change that occurs when an electron is added to a neutral atom to form a negative ion.OPTION B: Ionization energy is the minimum amount of energy required to remove an electron from its gaseous atom to form an ion. OPTION C: Electronegativity is a measure of an atom's ability to attract electrons to itself within a covalent bond.OPTION D: Potential energy is the energy that an object possesses as a result of its position or state and that is stored to be used when it is needed.

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.
