Question

Why do metals do not form compounds with hydrogen please explain.???

Answer 1

Metals do not form compounds with hydrogen because metals are electropositive and hydrogen is also electropositive....which means both release electrons....Metals release electrons and force hydrogen to accept it...but it also being electropositive rejects so no compound is formed...
....But some exception too...few metals form compounds with hydrogen also.....example Lithium...Sodium....Potassium..etc.



Thank You !!!

Answer 2

They do. Lithium aluminium tetrahydride and sodium boron tetrahydride are reducing agents, as the H- hydride ion is easily oxidized to H atoms or H+ions.
 lithium and aluminium, as well as most of all not all other main group metals, form hydrides. Most transition metals also form hydrides, by a variety of methods including by direct reaction with hydrogen. In addition, some transition metals can also form dihydrogen complexes, where the hydrogen molecule binds side-on to the metal without breaking the H-H bond.
