sodium is a metallic element, with the symbol of Na, which is located in the 3rd period and group 1A in the periodic table. It is a representative of alkali metal elements, soft in texture, and can react with water to generate sodium hydroxide, releasing hydrogen, with active chemical properties. Sodium is widely distributed in land and sea in the form of salt, and it is also one of the important components in human muscle tissue and nerve tissue.

Physical properties of sodium

Sodium is a silver-white cubic structure metal, which is soft and light and can be cut with a knife. Its density is .97g/cm, melting point is 97.81℃ and boiling point is 882.9℃. The new section has a silvery white luster, which is oxidized to dark gray in the air and has corrosion resistance.

Sodium is a good conductor of heat and electricity, and has a good magnetic conductivity. Potassium-sodium alloy (liquid) is a thermal conductivity agent for nuclear reactors. Sodium also has good ductility and low hardness, and can be dissolved in mercury and liquid ammonia, and dissolved in liquid ammonia to form a blue solution. Hardening at-2℃.
