Chemical Properties of Group IA Elements

CHEM-MFBWWD

Lithium forms lithium oxide, ${ Li }_{ 2 }O$, whereas other alkali metals of Group IA form peroxides or superoxides when reacted with oxygen.

This occurs because...

Select ALL that apply.

A

the ionization energy of lithium is largest among​ other alkali metals.

B

greater stability of ${ Li }_{ 2 }O $ is​ found in the solid state.

C

the lattice energy of ${ Li }_{ 2 }O$ is larger.

D

these oxides are ionic and peroxides are covalent compounds.​
