Energy is _ when an electron is added to the isolated gaseous atom.
Correct answer: B. Released
- A. Increased
- B. Released
- C. Decreased
- D. Absorbed
Explanation
The bonds of the atom are first broken to formindividual elements that then react with electrons. Bond breaking causes energy to be released.Energy is released when a electron is added to a nonmetal. Nonmetals have a greater electron affinity than metals because their atomic structure allows them to gain electrons rather than lose them

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.
