Would you expect the second electron gain enthalpy of Oxygen as positive, more negative or less negative than the first and why?

Options

  1. AMore negative because Oxygen is highly reactive
  2. BLess negative because Oxygen supports combustion
  3. CPositive because energy is needed to overcome the force of repulsion between a monovalent anion and a second i
  4. DPositive because Oxygen is a non-metal

Correct answer

C. Positive because energy is needed to overcome the force of repulsion between a monovalent anion and a second i

Step-by-step solution

Correct Option is : (C) Positive because energy is needed to overcome the force of repulsion between a monovalent anion and a second incoming electron
