Summary of the subject: "Atomic physics" - is the basis of the processes occurring in the microcosm, and the discipline taught to students on its basis is designed to give a deep understanding of the processes in an atom, molecule or solid. The discipline itself is a necessary prerequisite for such a special course as "Theory of Nuclear Reactors". Mastering such disciplines by students will ensure the formation of specialists in the specialty 143 Nuclear Energy with flexible thinking capable of solving not only narrowly specific problems in the future.

Критерії оцінювання результатів навчання: The procedure and criteria for assigning points and grades:
Theoretical questions are intended to test students' skills in understanding theoretical material. Answers should be as complete and reasoned as possible.
- The maximum number of points (mcp) for a question is given to a student who has fully covered the question;
- 70-90% of the marks - the question is generally covered, but there are minor inaccuracies or other shortcomings;
- 50-70% of the MCQs - the answer to the question is not given in full and / or there are significant errors;
- 30-50% of the MCQs - an attempt is made to answer the question, but gross mistakes are made and/or the question as a whole is not covered. The student will deserve the same mark if he/she draws incorrect conclusions based on logical assumptions that contain correct reasoning;
- 10-30% of the marks - an unsuccessful attempt is made to answer the question, only some of the reasoning and/or formulas are correct;
- 0 points - none of the written formulas is relevant to the question, all the reasoning is wrong or completely absent.
Problems are intended to test students' skills in practical solving of physical problems. Problems should be solved with the best possible explanation and, if necessary, with a figure.
- the maximum number of points (mcp) is given to the student who has completely solved the problem;
- 70-90% of the maximum marks are awarded for a solved problem with minor inaccuracies;
- 50-70% of the MCB - an error(s) was made in the solution that affected the result, but the approach to the solution was correct;
- 30-50 % of MCB - an attempt was made to solve the problem, but gross errors were made and the result is incorrect;
- 10-30 % of MCB - an unsuccessful attempt to solve the problem was made and one or more correct formulas related to the problem were written;
- 0 points - none of the written formulas is relevant to this problem, or the student did not even attempt to solve the proposed problem.
As a result, grades are assigned on a 100-point scale according to the following principle:
Excellent - 88 ... 100 points.
Good - 71 ... 87 points.
Satisfactory - 50 ... 70 points.
Unsatisfactory - 0 ... 49 points.
