Hi,
 
I have two questions

1) I'd like to know if the following reaction is possible is gaseous form for halogens

eg       I2 -> I+  +  I-

if so, please explain how? is transferring energy to the molecule by say laser or electron gun is sufficient or specific condition must be met?

2) I'd like to know whether having Ar+ and Cl- in the same space causes a chemical bond or just and attraction
I am aware that some noble gases form bonds with halogens but they mostly happen under extreme condition such as high pressure and temperature. am I correct to assume the aforementioned element won't combine in vacuum and under normal temperature?

Thank you

a) is possible but form easily the neutral molecule. Light is efficient.

b) would guide to neutral Argon and Chlorine radicals, but these form also neutral chlorine.

Ar⁺ + Cl^- => Ar + Cl^*

2 Cl^* => Cl₂
