Zelta;
Your right, it’s like asking what state of matter is gas in? – however I think I know what you are asking.
If we consider the gaseous state of matter as being atoms bouncing off one another as a result of radiation (heating), then we can view plasma as being the same thing except the radiation is self-generated due to the missing electrical charge.
This is about as simple as I can state it without going into the concepts of the behavior of charged particles which is probably what you had problems with while browsing. I personally do not view plasma as another state of matter but I do not object to those who do.
