Plasma State
Plasma State
Plasma is known as the fourth state of matter, distinct from solid, liquid, and gas.
Electron Behavior in Plasma
Electron Behavior in Plasma
In plasma, electrons are not bound to individual atomic nuclei and can move freely; unlike solids, liquids, and gases.
Plasma Ionization

Study Notes
Plasma and States of Matter
- Plasma is commonly referred to as the fourth state of matter, in addition to solid, liquid, and gas.
Electron Behavior
- In a solid, liquid, or gaseous sample of matter, electrons are closely bound to their atoms or molecules.
- In a plasma, electrons are free to move about, creating a collection of charged particles.
Defining Features of Plasma
- A defining feature of a plasma is the presence of ions and free electrons, which requires high temperatures to sustain.
Measuring Plasma Temperature
- Plasma temperature is commonly measured in electronvolts (eV) or Kelvin (K).
Low Temperature Behavior
- At low temperatures in a plasma, the ions and free electrons recombine, resulting in the loss of plasma properties.
