Dear Student

To prove that the sodium metal belongs to the group 1. It is reacted with water which on reaction gives sodium hydroxide and evolution of the hydrogen gas.
The reaction is as follows:
$2 N a + 2 H_{2} O \to 2 N a O H + H_{2}$
This reaction is the characteristic reaction of group 1 and hence sodium metal belongs to group 1.
