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

Below are typical molecular compounds formed by Sodium interacting with other elements:

NaCl (Sodium Chloride)NaHCO₃ (Sodium Bicarbonate)NaOH (Sodium Hydroxide)
