In this article, the place of aluminum in the periodic table and its physical and chemical properties, which is one of the elements belonging to group III A of the periodic system, is studied. Aluminum is a metal with atomic number 13 in the third period and group III A of the periodic table. This article analyzes properties of aluminum such as atomic structure, ionization energy, electronegativity and oxidation state. Aluminum's physical properties, including density, melting and boiling points, electrical and thermal conductivity, and chemical behavior, are also discussed extensively. In particular, its passivation under the influence of the atmosphere and resistance to corrosion are shown as one of the important aspects. The article also briefly covers the importance of aluminum in industry and technology, its extraction and processing.

"The harmony in Navoi's books begins in their introduction. The introduction to each of his works is adapted to the content of this work," writes academician Alibek Rustamov (6, 147). The same comments of a famous scientist have great scientific value. Alisher Navoi's works cannot be fully imagined without separating chapters and seasons from each other. More precisely, they form a single living organism. In order to know the main content of symbolic allusions and other pictorial means, and to get detailed information about them, it is necessary to have the full text of the artistic work at the disposal of the reader. The same remark applies to the fourth epic of Hazrat Alisher Navoi's "Khamsa" "Sabai Sayyar". This romantic-adventure saga created on the basis of the myth of "Bahromi Gore", which is widespread in the East, was published in the current spelling only with the honor of Independence.
