School of Physics and Technology of University of Kharkiv now being carried by the department. The department is considered to be the most difficult department at the school. Students of the department study special courses on elementary particles, quantum electrodynamics, general relativity, astrophysics, theoretical nuclear physics, solid-state theory, and plasma physics. In addition, the professors of the department teach most of the bachelors-level mathematics and theoretical physics courses at the school. The department was created in 1937 by Anton Valter. The name of the department changed several times: "Department of Physics of the Atomic Nucleus", "Department of Physics of the Atomic Nucleus and Electronics", "Department of Electronic Processes", "Department
Electron affinity Electron affinity In chemistry and atomic physics, the electron affinity ("E") of an atom or molecule is defined as the amount of energy "released" or "spent" when an electron is added to a neutral atom or molecule in the gaseous state to form a negative ion. In solid state physics, the electron affinity for a surface is defined somewhat differently (see below). This property is measured for atoms and molecules in the gaseous state only, since in a solid or liquid state their energy levels would be changed by contact with other atoms or molecules. A list of the electron
