naatriumiatom

Naatriumiatom refers to an atom of the chemical element sodium. Sodium, with the chemical symbol Na and atomic number 11, is a highly reactive alkali metal. In its atomic state, a sodium atom consists of a nucleus containing 11 protons and typically 12 neutrons, surrounded by 11 electrons. These electrons are arranged in shells, with the outermost electron residing in the third electron shell. This single valence electron is loosely bound, making sodium eager to lose it to achieve a stable electron configuration. This characteristic makes sodium readily form a positive ion, Na+, by donating this outermost electron. Pure sodium metal is soft, silvery-white, and tarnishes rapidly in air due to its reactivity. It is never found in its elemental form in nature but rather as compounds, most commonly sodium chloride (table salt). The properties of the naatriumiatom dictate sodium's behavior in chemical reactions and its role in various biological and industrial processes.
