Sodium and oxygen: (room temperature) 4Na+O2=2Na2O; (ignition) 2Na+O2=Na2O2. Sodium reacts with water:

2na+2h2o=2naoh+h2↑。Sodium reacts with sulfuric acid: 2Na + H2SO4 = Na2SO4 + H2.

Sodium oxide reacts with water: Na2O+H2O=2NaOH. Sodium peroxide reacts with carbon dioxide:

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

Sodium is a silvery-white cube structure metal, soft and light can be cut with a knife, the density is smaller than water, is, melting point, boiling point 883. The new facet has a silvery-white luster, which oxidizes in the air and turns into a dark gray color, which is corrosion-resistant. Sodium is a good conductor of heat and electricity and has good magnetic conductivity, and potassium-sodium alloy (liquid state) is a thermal conductive agent for nuclear reactors.

Sodium element also has good ductility and low hardness, and can be soluble in mercury and liquid ammonia, and soluble in liquid ammonia to form a blue solution. Hardens at -20.
