Question

Write the names and formulae of (a) a metal hydride, and (b) a non-metal hydride.

Answer 1

Answer:

metal hydride- NaH(Sodium Hydride)

non metal hydride- sulphur hydride

Answer 2

Explanation:

a) Formation of new compound when metals get bonded to a hydrogen compound is called as metal hydride.

• It is used in fuel cell applications. Mostly, these bonds are covalent but some from ionic type also.
• The oxidation number for hydrogen is -1 and forms hydride if the gas absorbed by metals. Some name and formulae of the metal hydrides are as follows:

• $LiH$ – Lithium Hydride
• $CaH_2$ – Calcium Hydride
• $AlH_3$ – Aluminium Hydride
• $GeH_4$ – Germanium Hydride
• $SnH_4$ – Tin Hydride

b) Hydrogen reacts with non- metals to form covalent/non-metal hydride. It is done by sharing of atom’s electron pair and this kind of hydride volatile in nature. Some name and formulae of the non-metal hydrides are as follows:

• $NH_3$ - Ammonia

• $H_2 O$ – Water
• $H_2 S$ – Hydrogen Sulphide .
