Recently I have been reading about the fourth state of matter, viz.Plasma. Everywhere I read that plasma is formed when Gases are given enough energy and they lose their electrons to form a "cloud" of free electrons and cations i.e. when gases are ionised.
In a plasma ball, the gas inside the ball is a noble gas. Even though noble gases are chemically inert and won't lose electrons much easily, as compared to other gases I am unable to understand why are they used ?
(Please correct me if I am wrong somewhere.Thank You.)
