Plasma

In Physics and Chemistry, plasma is an energetic state of atomic matter where some electrons in the outer orbitals have become separated.

Three lower energy phases of matter are solid, liquid, and gas. Everyday forms of plasma are the sun, which is a sphere of plasma heated by nuclear fusion, and fluorescent and neon Electric lights which use plasma to excite phosphors? that emit visible light.
