Rubidium amide is a chemical compound made of rubidium , nitrogen and hydrogen .
Manufacturing
Rubidium amide is formed when the metal is heated in the ammonia stream.
It is also formed by the reaction of rubidium hydride with liquid ammonia with evolution of hydrogen. The reaction with gaseous ammonia takes place very slowly at room temperature.
When heating rubidium in a nitrogen stream arises also Rubidiumamid, as a byproduct, however, is in no small quantities Rubidiumnitrid .
