The Elements: Sodium

Sodium is a highly reactive element that forms a layer of sodium oxide when exposed to air. It reacts vigorously with water and does not exist in its pure form naturally. Instead, it forms compounds like baking soda and salt. Sodium is essential in our diet for controlling blood pressure and nerve function, but excessive intake can lead to health issues. It is widely used in industries such as glass, paper, and soap manufacturing. Sodium is the sixth most abundant element on Earth, making up a significant portion of the planet's crust and is found in all seas and oceans.
