Sodium (Na) is placed in Group 1 of the periodic table and is classified as an alkali metal due to its high reactivity and ability to form alkaline hydroxides with water. The alkali metals share similar properties, including having one electron in their outer shell. Sodium's notable reactivity and formation of basic compounds are key factors in its classification. ;
Sodium (Na) is located in Group 1 of the modern periodic table and is classified as an alkali metal due to its reactivity and ability to form alkaline hydroxides with water. Alkali metals are characterized by their single outer electron that they readily lose, making them very reactive. Sodium's reactions, particularly with water, highlight its classification as an alkali metal.
