Sodium vs. Sodium Oxide
What's the Difference?
Sodium is a highly reactive metal that is commonly found in nature as a compound, such as sodium chloride (table salt). When sodium reacts with oxygen, it forms sodium oxide, a white solid that is also highly reactive. While sodium is a soft, silvery metal that is easily cut with a knife, sodium oxide is a brittle solid that is not conductive of electricity. Both sodium and sodium oxide are important compounds in various industrial processes and have a wide range of applications in chemistry and materials science.

Further Detail
Introduction
Sodium and sodium oxide are two chemical compounds that have distinct properties and characteristics. In this article, we will compare the attributes of sodium and sodium oxide to understand their differences and similarities.
Physical Properties
Sodium is a soft, silvery-white metal that is highly reactive and can be easily cut with a knife. It has a melting point of 97.79°C and a boiling point of 882.9°C. Sodium oxide, on the other hand, is a white solid that is also highly reactive. It has a melting point of 1,132°C and a boiling point of 1,950°C. Both sodium and sodium oxide are soluble in water.
Chemical Properties
When exposed to air, sodium quickly reacts to form a layer of sodium oxide on its surface. This oxide layer protects the underlying metal from further oxidation. Sodium oxide, on the other hand, is a powerful oxidizing agent that can react with a wide range of substances. It is commonly used in the production of glass and ceramics.
Reactivity
Sodium is known for its high reactivity, especially with water. When sodium comes into contact with water, it reacts vigorously to produce hydrogen gas and sodium hydroxide. This reaction is highly exothermic and can result in the ignition of the hydrogen gas. Sodium oxide, on the other hand, is less reactive than sodium but still exhibits strong oxidizing properties.
Applications
Sodium is used in a variety of applications, including the production of chemicals, pharmaceuticals, and metal alloys. It is also used as a coolant in nuclear reactors and as a reagent in organic synthesis. Sodium oxide is primarily used in the manufacturing of glass, where it serves as a flux to lower the melting point of silica.
Toxicity
Sodium is an essential element for human health and is found in many foods. However, excessive consumption of sodium can lead to health problems such as high blood pressure and heart disease. Sodium oxide, on the other hand, is highly toxic and can cause severe irritation to the skin, eyes, and respiratory system. It should be handled with care and proper safety precautions.
Conclusion
In conclusion, sodium and sodium oxide are two chemical compounds with distinct properties and characteristics. While sodium is a reactive metal with various industrial applications, sodium oxide is a powerful oxidizing agent used primarily in the production of glass. Understanding the differences between sodium and sodium oxide is essential for their safe handling and use in various industries.
