Binary compounds of various elements wit...

Binary compounds of various elements with hydrogen where hydrogen exhibit an oxidation number of (-1) are called binary hydrides. Nature of hydride obtained depends upon electronegativity of the element and hence on the type of bond formed Hydrides are mainly of three classes
Ionic, saline or salt like hydrides.
Covalent or Molecular hydrides.
Metallic or interstitial hydrides.
Which of the following form metallic hydrides ?

A

Mn

B

Fe

C

Pb

D
