Can the charged particles in a gas or plasma be negative ions / cations?
Can the charged particles in a gas or plasma be negative ions / cations? Or are they always anions, and it's only solids and liquids that can (also) be cations?
Any input would be GREATLY appreciated!

Yes. They can be. electrons get attached to any body. You get negative charged gas molecules.

Let's look at the dfinition of 'plasma':
Plasma (from Ancient Greek πλάσμα, meaning 'moldable substance') is one of the four fundamental states of matter, and was first described by chemist Irving Langmuir in the 1920s. It consists of a gas of ions, atoms which have some of their orbital electrons removed, and free electrons.
atoms which have some of their orbital electrons removed, and free electrons
So the both positive and negative.
