Properties Of Sodium

Sodium being cut with a knife.

Sodium is an alkali metal. Alkali metals are are all shiny, soft, highly reactive metals at standard temperature and pressure and readily lose their outermost electron. Sodium is a soft metal. Sodium is even soft enough that it can be cut with a knife. Sodium is also a very reactive metal, it even reacts to the water in the air. When the soft metal and air react the sodium turns white and chalky on the outside. However, when you cut the soft metal, you could see that in the inside it is shiny.

Sodium is reactive to the water in the air so people have to store in oil.

This video can show you how reative sodium can be with water.
