Yes, MgH2 is a metallic hydride because it is a compound formed between a metal (Mg) and hydrogen (H). Metallic hydrides have characteristics such as high hydrogen storage capacity and can release hydrogen gas under certain conditions.
Magnesium hydride, also known as MgH2, is a white, crystalline solid that is used as a hydrogen storage material. It can release hydrogen gas when heated, making it a promising candidate for fuel cell applications.

There are three types of hydride: saline, metallic and covalent (there are alternative names for the types of hydride, but these are most common). Saline hydrides have crystalline, salt like structures, and are formed with hydrogen and the group 1 and group 2 metals (the alkali metals and the alkaline earth metals). Metallic hydrides are brittle solids with fairly simple structures, generally formed between hydrogen and the transition metals. They can often have non-integer stoichiometries, e.g. ZrH1.3. Covalent hydrides are formed between hydrogen and the p-block elements, and tend to be gases as room temperature (there are exceptions to this, because of hydrogen bonding).
Sodium hydride is an ionic compound.
The formula of the hydride formed with magnesium is MgH2.
Magnesium hydride, MgH2
Ionic bond. Magnesium (Mg) donates two electrons to hydrogen (H), resulting in the formation of magnesium hydride (MgH2) through ionic bonding.
Magnesium hydride, also known as MgH2, is a white, crystalline solid that is used as a hydrogen storage material. It can release hydrogen gas when heated, making it a promising candidate for fuel cell applications.
Magnesium and hydrogen
In MgH2, since magnesium is always assigned a +2 oxidation state and hydrogen typically has a -1 oxidation state, the oxidation number of hydrogen in MgH2 is -1.

There are two main types of binary compounds of hydrogen: hydrides and hydrogen halides. Hydrides contain hydrogen and one other element, such as lithium hydride (LiH). Hydrogen halides are compounds formed when hydrogen combines with a halogen element, like hydrogen chloride (HCl).
No, ammonia is commonly called NH4OH, or ammonium hydroxide. However in actual fact it is a NH3 + H2O solution. There is no metal (or metal ion) present.
