This document is the complete Tutorial 1 support for Atomic Structure, designed for 1st year Medicine and Dental Medicine students. It covers the entire chapter, from the Bohr model to polyelectronic atoms, in five progressive sections: Bohr's postulates and energy levels, generalisation to hydrogen-like ions, electronic transitions and spectral series, Slater's rules and screening, and cross-topic synthesis exercises. A detailed answer key accompanies each question, with methodological callouts, calculation tips, and warnings against common mistakes. Designed for independent learning, this document enables students to practise, check their answers, and consolidate their knowledge.

Keywords: Atomic structure, Bohr model, Hydrogen-like ions, Spectral series, Slater's rule, Effective nuclear charge, Tutorial with answer key.
