Question

Which metal does not form hydride on reaction with h2?

Answer 1

Answer:

Most of the metals do not react with hydrogen . Only a few reactive metals react with hydrogen to form metal hydrides . For example : When Hydrogen gas is passed over heated sodium , then sodium hydride is formed .

b) Non-metals react with hydrogen to form covalent hydrides . For example : Sulphur combines with hydrogen to form Hydrogen sulphide .

Answer 2

Answer:

Most of the metal do not react with hydrogen because metals form compound by losing electrons and hydrogen also loses the eletrons and forms compounds.so normally hydrogen atom does not accept electrons given by a metal atom to form a compound
