Plasma is subatomic structure.
Here, read up on the facts.
www.viewsfromscience.com...
A plasma is a distinct state of matter containing a significant number of electrically charged particles, a number sufficient to affect its electrical properties and behavior.

Do you see the problem with the question and the definition?

Is this an accurate definition of plasma:
A plasma is a distinct state of matter containing a significant number of electrically charged particles, a number sufficient to affect its electrical properties and behavior.

. . . sufficient to affect its electrical properties and behavior.

Unlike gases, plasmas are electrically conductive, produce magnetic fields and electric currents, and respond strongly to electromagnetic forces.

sorry the universe disagrees with you.
By the way humans produce heat light and guess what electricity as well so i guess were plasma as well.

. . . although they would need protons to be electrically neutral, in the structure of plasma.

Yes, it is so unscientific to speculate and hypothesize.
Especially when you all ready know all the answers.
I read that and I've had ice cubes in my drink and I call that a liquid with solid ice cubes in it. But my point about plasma is the definition would be more clear if it was defined the way you are implying, that if we could say a mixture of 99% gaseous uncharged particles and 1% charged particles was 99% gas and 1% plasma, but we don't use plasma that way...we call the whole thing a plasma. Part of the reason for this is that the charged particles have some properties similar enough to a gas that it mixes readily with a gas, which is why I couldn't understand you denying it was similar to a gas. Other properties of course like the ability to conduct electricity distinguish the two, but the fact remains that if the plasma is 100% charged particles it will be more conductive than if it's only 1% charged particles..

Did you read this in my previous post?
"Just as there are gases and liquids in solids, solids and gases in liquids, and solids and liquids in gases, there is also the fourth state of matter, plasma."
Right. This is what I've been trying to say to illustrate the idea that what we call "plasma" can be so similar to gas we can't even find where one begins and the other ends in our atmosphere.

The thing about our atmosphere is that there is no definitive boundary, like the surface or the ocean, where the gas ends and the plasma begins.
I don't know what leads you to that idea. You can put an electrically neutral permanent magnet in a vacuum chamber, and remove any charged particles from around the magnet. and it will still have a magnetic field so this would easily prove that idea false, wouldn't it? But yes plasma is ubiquitous in the universe, except for little pockets like the surface of the Earth where we live, where it's not so easy to find in nature except lightning etc.
Essentially, plasma is everywhere. I think eventually, we will find out that a magnetic field is a form of a plasma structure.

This part is probably the part that is significant for all practical purposes:
That doesn't draw any kind of line at low concentrations of charged particles because Experiment A might show electrical properties and experiment B may not, on the same matter. Maybe pictures will help illustrate why I say it's not so distinct. First, look at the phase diagram for solid, liquid and gas and note there is a thin line separating them:

A hydrogen atom is electrically neutral. Split the proton from the electron and the two still cancel each other out from a distance, so still neutral overall, but now the electron can conduct electricity which it couldn't do when it was bound to the hydrogen atom.
Plasma is loosely described as an electrically neutral medium of positive and negative particles (i.e. the overall charge of a plasma is roughly zero). It is important to note that although they are unbound, these particles are not ‘free’. When the charges move they generate electrical currents with magnetic fields, and as a result, they are affected by each other’s fields.

Generating electrical currents with magnetic fields is considered electrically neutral?
