Let electronegativity, ionisation energy and electron affinity be represented as EN, IP and EA respectively. Which one of the following equation is correct according to Mulliken?

Options

  1. AEN = IP EA
  2. BEN = IP EA
  3. CEN = IP + EA 2
  4. DEN = IP - EA

Correct answer

C. EN = IP + EA 2

Step-by-step solution

Mulliken suggested that EN of an element is the average of its IP and EA.
