About Sodium
Sodium is a soft, silvery-white, highly reactive metal. It is the sixth most abundant element in Earth's crust. Sodium ions are essential for nerve signal transmission and muscle contraction. It was first isolated by Humphry Davy through electrolysis of sodium hydroxide.
Gebruiks & Programme
Table salt (NaCl), street lighting, soap manufacturing, de-icing roads, baking soda, and as a coolant in nuclear reactors.
Fun Fact
Sodium reacts so violently with water that it can explode, yet the sodium ion is absolutely essential for human life.
