4th Period: Potassium and Calcium—Electrons go into the fourth energy level. A small piece of sodium metal is placed in water. The sodium reacts with the water and gets very hot, producing sodium ...

The apparatus below is used to react calcium with water and collect the gas. This would not be used with sodium or potassium as they float and the reaction is too vigorous.

Sodium would react very quickly with water to produce hydrogen gas in an exothermic reaction (a reaction that transfers energy to the surroundings). This would happen whenever the cutlery was put ...

When sodium reacts with water, it can lead to violent explosions, as demonstrated in Prathap's case. This article will explore the reactions of sodium with water, the potential dangers involved ...

A small piece of sodium metal is placed in a flask of chlorine gas. A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic ...
