What type of matter is plasma classified as?

Plasma is classified as an ionized gas with free electrons. This state of matter occurs when a gas is energized to the point that electrons are stripped away from atoms, leading to the formation of ions and free electrons. Unlike other states of matter, such as solids or liquids, plasma can conduct electricity and is influenced by magnetic fields due to its charged particles. This makes it distinct from neutral gases, where electrons remain bound to their atoms, and from the other states of matter that either lack significant mobility (solids) or retain a fixed volume while flowing (liquids). Plasma is commonly found in stars and neon signs, illustrating its unique characteristics and behavior in the universe.
