Generally, elemental sodium is more reactive than lithium, and it reacts with water to form a strong base, sodium hydroxide (NaOH).

Why sodium is a reactive element?

A metal is said to be reactive if it is highly electropositive in nature and readily loses its electrons in a reaction. Sodium metal has very low ionization energy and therefore readily loses its electron.

Is the element sodium highly reactive?

Sodium is highly reactive, forming a wide variety of compounds with nearly all inorganic and organic anions (negatively charged ions).
