what are hydrides and oxides ?

Hydrides are those compounds in which hydrogen is bonded to an element. These compounds contain at least one hydrogen in its chemical formula. The chemical formulae for some element hydrides are:

RH: e.g., LiH, NaH

RH2:MgH2,H2O ,H2S

RH3: NH3,BH3,PH3

RH4:CH4  where R  denotes the element.

Oxides are the chemical compounds in which oxygen is bonded to an element. These compounds contain at least one oxygen atom in its chemical formula. The chemical formulae for some element oxides are:

R2O: Li2O, Na2O K2O

RO:  MgO , ZnO

R2O3: Al2O3

RO2: CO2, SiO2

R2O5: N2O5

RO3: SO3

R2O7: Cl2O7   where R  denotes the element.

 Hydride is the anion of hydrogen, H, or, more commonly, a compound in which one or more hydrogen centres have nucleophilic, reducing, or basic properties. In compounds that are regarded as hydrides, hydrogen is bonded to a more electropositive element or group.

An oxide  is a chemical compound that contains at least one oxygen atom in itschemical formula. Metal oxides typically contain an anion of oxygen in the oxidation state of −2.

A hydride is a compound of hydrogen with another element or elements, typically an alkali or alkaline earth metal. They're used as sources of hydrogen in chemical reductions, batteries, and for hydrogen storage at low pressures.

 

An oxide is a

chemical compound

containing

at least one oxygen

atom as well as

at least one other element

. Ex. Carbon Dioxide (One carbona atom, two [di] oxygen atoms).
