# Temperature and energy of ions and electrons at Ionization

For Xenon atom, as the ionization energy is 12.13 eV , does it mean that if 12.13 V is applied, the Xenon atom can be ionized. Also, Could you share, how to find the temperature and energy of electron, the atom and ion at this low voltage.

I am not sure if I can use $E= 3/2 k_B T$

Thank you
