Sodium is a metal element, the symbol is Na, and the English name is sodium. It is located in the third period of the periodic table of elements and family IA, and is the representative of alkali metal elements. Soft texture, can react with water to generate sodium hydroxide and release hydrogen, and its chemical properties are relatively active.
Nature:
Sodium is very active chemically. Combined with oxygen at room temperature and heating, it reacts violently with water and explodes in large quantities. Sodium can also burn in carbon dioxide, react with lower alcohols to generate hydrogen, and react with liquid ammonia with weak ionization ability.
Sodium exists as a compound in nature. It is widely distributed. Sodium is rich in albite (NaAlSi3O8), salt (sodium chloride), Chilean saltpeter (sodium nitrate), soda ash (sodium carbonate) and other minerals.
