Explain why the surface of sodium is only shiny when it is freshly cut?
The shiny appearance of freshly cut sodium is due to its high reactivity with oxygen in the air. When sodium is exposed to air, it quickly reacts with oxygen to form sodium oxide, which creates a dull, opaque layer on the surface of the metal. This layer of sodium oxide obscures the shiny surface of the metal, giving it a dull appearance. Therefore, only freshly cut sodium displays its characteristic shiny appearance before it reacts with oxygen in the air.
What causes the surface of sodium of pottasium to go dull when it is cut?

When sodium metal is exposed to air, it reacts with oxygen to form sodium oxide and sodium hydroxide.

It is the reaction with oxygen in the air that causes the shiny metal to become dull shortly after being cut.
Why is it when you cut s piece of sodium metal the shiny metal soon goes dull?
When a piece of sodium metal is cut, it is exposed to air, which contains moisture and oxygen. This leads to the formation of sodium oxide and sodium hydroxide on the surface of the metal, which gives it a dull appearance. The shiny surface of the sodium metal reacts with the surrounding air and moisture, forming these compounds which are not shiny.
