A plasma is a partially or completely ionised gas containing electrons, ions, excited and ground state atoms and/or molecules, reactive free radicals and photons 

Plasmas are a lot like gases, but the atoms are different, because they are made up of free electronsand ions of an element such as neon(Ne). You don't find naturally occurring plasmas too often when you walk around. They aren't things that happen regularly on Earth.

In a plasma, some electrons are freed from their atoms, allowing current and electricity to flow. Plasmas and nuclear fusion Fusion is the process occurring within the plasma core of our Sun in which the nuclei of lighter atoms link to form a heavier atom. For example, when hydrogen nuclei collide, they can fuse into heavier helium nuclei and release tremendous amounts of energy in the process. Plasma is a gas were all the atoms have been split into electrons, protons and neutrons. So it is like a soup of electrons, protons and neutrons all mixed together but not structured in atoms. This means that a plasma ‘cloud’ behaves as a whole instead of behaving as a bunch of individual atoms. Plasma (from Ancient Greek πλάσμα 'moldable substance') is one of the four fundamental states of matter, and was first described by chemist Irving Langmuir in the 1920s.

What we see as light and feel as warmth coming from the Sun is the result of this fusion reaction process. Inductively coupled plasma mass spectrometry is a type of mass spectrometry that uses an Inductively coupled plasma to ionize the sample. It atomizes the sample and creates atomic and small polyatomic ions, which are then detected.

Like gases, plasmas have no fixed shape or volume, and are less dense than solids or liquids. But unlike ordinary gases, plasmas are made up of atoms in which some or all of the electrons have been Plasma (from Ancient Greek πλάσμα 'moldable substance') is one of the four fundamental states of matter, first systematically studied by Irving Langmuir in the 1920s. It consists of a gas of ions – atoms or molecules which have one or more orbital electrons stripped (or, rarely, an extra electron attached), and free electrons.

electromagnetic fields). Plasmas If most of the atoms or molecules in a region are ionized, the resulting state of matter corresponds to a gas that is electrically neutral on a global scale, but composed microscopically of positively charged ions and the negatively charged electrons stripped from the atoms to form the ions. Such a state of matter is called a plasma. 2001-11-25 2019-02-09 Plasma Atomic Physics provides an overview of the elementary processes within atoms and ions in plasmas, and introduces readers to the language of atomic spectra and light emission, allowing them to explore the various and fascinating radiative properties of matter.

These manipulations cause the proxy atoms to interact strongly, leading to organised structures – plasma crystals.
