- Sodium is a soft, silvery-white metal.
- It is highly reactive, particularly with water and halogens.
- Sodium has a low melting point (97.79 °C) compared to other metals.
Physical and Chemical Properties of Sodium
Sodium has distinct physical and chemical properties that define its classification as a metal. Here are some notable properties:
Physical Properties
- State: Solid at room temperature.
- Color: Silvery-white metallic luster.
- Density: Approximately 0.97 g/cm³, making it less dense than water.
- Melting Point: 97.79 °C.
- Boiling Point: 883 °C.
Chemical Properties
Sodium exhibits several chemical properties that are typical for metals:
- Highly reactive, especially with water, producing sodium hydroxide and hydrogen gas.
- Forms various compounds, such as sodium chloride (table salt).
- Oxidizes quickly in air, forming sodium oxide.
