1.	what do you understand by “Non stoichiometric hydrides”? Do you think this type of hydrides to be formed by alkali metals? Justify your answer.
Answer» Hydrides which are deficient in hydrogen and in which the ratio of hydrogen to metal is fractional are called non-stoichiometric hydrides. This type of hydrides are formed by d-and f-block element. Since alkali metals are highly reducing, they transfer their own electron to H atom thereby forming H- ion. Therefore the ratio of metal to hydrogen is always fixed and they form only stoichiometric hydrides. In other words alkali metals do not form non-stoichiometric hydrides.

Hydrides which are deficient in hydrogen and in which the ratio of hydrogen to metal is fractional are called non-stoichiometric hydrides. This type of hydrides are formed by d-and f-block element.

Since alkali metals are highly reducing, they transfer their own electron to H atom thereby forming H- ion. Therefore the ratio of metal to hydrogen is always fixed and they form only stoichiometric hydrides. In other words alkali metals do not form non-stoichiometric hydrides.
