Physical Properties of Sodium
- The metallic luster of sodium is very strong. The color is very similar to silver.
- At room temperature, it becomes soft enough to be pressed with a finger into a leaf shape.
- Sodium compounds change color more slowly in the air than potassium compounds.
- In the air, sodium reacts with oxygen to form sodium oxide, which combines with water vapor to form a film of sodium hydroxide.
Uses of Sodium
- Additionally, it is used to clean soaps, molten metals, and sodium vapor lamps, and improve the structure of some alloys.
- Sodium is a component of sodium chloride, an important substance in the environment that supports life.
- Both the formation of esters and the formation of organic molecules are sodium-dependent.
- Solid sodium carbonate is required for the manufacture of glass.
Calculate the number of atoms in 46g of Na.
46g of Na contains 12.044 x 1023 atoms. Sodium is very strong and is a similar color to that silver. It becomes soft and changes color when exposed to air.
