65. What is meant by electro negativity of SF6 gas? SF6 has high affinity for electrons. When a free electron comes and collides with a neutral gas molecule, the electron is absorbed by the neutral gas molecule and negative ion is formed. This is called as electro negativity of SF6 gas. 66. What are the characteristic of SF6 gas?
