Explanation / Answer

Part:A;

It is zirconium hydrde (ZrH)

Part-B :

in this hydride

the A is attached to three hydrogen atoms

we know that

the electronic configuration of phosphorus is

1s2 2s2 2p6 3s2 3p3

so it forms to fullfil octet rule

so

phosphorus can form three bonds

So

the formula of the hydride is PH3

Part : C

similarly bromine required one elctron toe fullfil octet rule

so it can from one bond

so

the given hydride is BrH

Part;D

we can see that

in the figure

one A is surrounded by 4 H atoms

also

one H is surrounded by 4 A atoms

so

the formula is AH

now

we know that

Lithium can only form a single bond with Hydrogen

so

It is the a crystal strucutre of Lithim hydride

so

the chemical formula of hydride is LiH
