What Electric Field is Needed to Ionize Neon at Atmospheric Pressure?

[alex_thaiboy]

What is a first order approzimation for the electric field to ionize neon? (ioniztion energy 22eV) at atmospheric pressure?
Hint: The probability of collision of the electron with the gas molecule is called electron mean free path. The mean free path of the electron at atmospheric pressure in Ne gas is about 20*10^-6 m. This means the electron will gain energy over 20*10^-6m.
