Origin & Abundance
Discovery Details
Discovered by Humphry Davy in the year 1807.
Natural Occurrence
Extremely abundant combined in oceans as dissolved NaCl (salt). Highly reactive, stored in mineral oil to prevent reaction with air/moisture.
Common Uses & Applications
- Table salt seasoning
- Sodium-vapor street lamps
- Heat transfer fluid in nuclear reactors
- Baking soda (Sodium bicarbonate)
