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
Atomic theory example, in the case of Proust's tin oxides, one tin atom will combine with either one or two oxygen atoms to form either the first or the second oxide of tin. Dalton believed atomic theory could explain why water absorbed different gases in different proportions - for example, he found that water absorbed carbon dioxide far better than it absorbed nitrogen. Dalton hypothesized this was due to the differences in mass and complexity of the gases' respective particles. Indeed, carbon dioxide molecules (CO) are heavier and larger than nitrogen molecules (N). Dalton proposed that each chemical element is composed of
