In the presented review, the current progress on the investigation of monolayered films is considered as the topical subject of the modern physics and chemistry of two-dimensional materials. Structure and properties of atomically thin monoelemental films such as 2D iron, gold, lithium as well as silicene, germanene, borophene, etc. are described in detail. Two-dimensional films of metallic compounds such as iron, copper, and zinc oxides, iron, cobalt, and copper carbides are reviewed as well. The main approaches to monoatomic films stabilization inside the pores or between the layers of other 2D materials are presented, and exfoliation mechanism of ionic-covalent films with polar surface into weakly bounded monolayers is thoroughly considered.
