Answer 2

Hey dear,

● Answer -
Formula of metal hydride is H2S.

● Explaination -
- Elements bond with hydrogen to form their hydrides.
- Element forming MF4 & MF6 must be sulphur.
- Sulphur forms both sulphur tetrafluoride & sulphur hexafluoride.
- Sulpur reacts with hydrogen to form its hydride, hydrogen sulphide.
- Therefore, formula of metal hydride is H2S.
