As a chemical expert with a focus on inorganic elements, I'm here to provide you with a comprehensive answer regarding the cost and availability of pure sodium.

Sodium, an alkali metal, is incredibly reactive due to its single electron in the outer shell. This reactivity means that it readily forms compounds with other elements, which is why it is never found in its elemental form in nature. Instead, sodium is found in various compounds such as sodium chloride (table salt), which is one of the most common forms in which sodium is encountered.

When it comes to the cost of pure sodium, it's important to consider both its purity and the quantity being purchased. The cost can vary significantly depending on these factors. For pure sodium, the cost is approximately $25 per 100 grams. This price point reflects the high demand for sodium in various industrial applications, as well as the costs associated with its production and handling.

Sodium is the sixth most abundant element on Earth and is particularly abundant in the Earth's crust and in the oceans. It is also found in various minerals and is a key component of many biological systems, playing a crucial role in nerve function and muscle contraction.

The production of pure sodium is a complex process that involves the electrolysis of molten sodium chloride. This process requires a significant amount of energy and specialized equipment, which contributes to the cost. Additionally, due to its reactivity, pure sodium must be stored under specific conditions to prevent it from reacting with air or moisture, further adding to the overall cost.

In terms of purchasing sodium in bulk, the cost per 100 grams can be significantly less than the pure form due to economies of scale and the potential inclusion of impurities. However, for many applications, especially in research and high-precision manufacturing, the purity of the sodium is critical, and thus the higher cost is justified.

It's also worth noting that the price of sodium can fluctuate based on market conditions, availability of raw materials, and changes in production technologies. For the most accurate and up-to-date pricing, it's recommended to consult with suppliers or check commodity exchange listings.

In summary, pure sodium is a valuable and versatile element with a cost that reflects its reactivity, production complexity, and wide range of applications. The price of $25 per 100 grams for pure sodium is a baseline figure, but the actual cost can vary based on purity, quantity, and market conditions.
