Sodium Physical Properties

These properties are defined majorly by observations or with a measuring instrument and are referred as surface or physical properties. Sodium physical properties are one of the most important properties of this metal. Physical properties of Sodium include melting point, boiling point, mechanical strength, optical properties and its appearance. We have tried to include all physical and Chemical Properties of Sodium metal here.

Melting Point of Sodium

The melting point is a fundamental parameter that constitutes the physical properties of Sodium. Melting point of Sodium is the temperature at which it changes from its solid state to a liquid state, at constant atmospheric conditions. Generally, the term 'melting point' and 'freezing point' are used interchangeably, depending on the state change. Simplifying, if the metal is heated from its solid state to a liquid state by supplying heat, melting point is referred, while during cooling (heat removal) when the metal turns solid from its liquid state the term freezing point is used. Sodium's melting point is 97.72 °C.

Boiling Point of Sodium

Boiling point of Sodium is the temperature at which it changes from a liquid state into vapors at constant atmospheric pressure. Sodium boiling point is 883.00 °C. Interestingly, there are few parameters that can alter this behavior. Have you ever surprisingly noticed why water boils sooner at your trek base camps, where the altitude is few thousand meters above the sea level? It is because, the boiling point is generally influenced by factors like altitude, pressure, molecule size and the concentration. Those phenomena are covered under the Sodium. Sodium melting point & its boiling point are two very prominent aspects of its physical properties. Speed of Sound of Sodium is 3,200.00 m/s

Sodium Element Appearance

The appearance is the primary consideration when it comes to making sculptures and designs. Physical properties of Sodium also include Sodium Element appearance which means how this metal appears at room temperature. Few metals are lustrous while few others are not. Few metals have shiny silver/metalic color, few others are reddish brown while few have a yellowish gloss. All these factors explain the overall look of the metal surface. Sodium metal at room temperature is in Solid state and has Silvery White with Metallic luster and finish of the outer surface. Knowing further, the physical properties also affect the Atomic Structure of Sodium.

Optical properties and Hardness of Sodium (Na)

Optical properties and hardness of Sodium (Na) include phenomenon such as refractive index, reflectivity, different hardness scales. Refractive index of Sodium is Not Available. Hardness of Sodium is its ability to resist compression force applied externally. Hardness of Sodium metal according to Mohs Hardness, Brinell Hardness and Vickers Hardness is 0.50, 0.69 MPa and Not Available respectively. All these characteristics of Sodium are also called as the physical properties of Sodium.
