Question

Give the formulae of the stable binary compounds that would be formed by the combination of the following pair of elements.

Lithium and Oxygen

Answer 1

Binary compounds:

• Binary compounds are chemical compounds that comprise two different chemical elements.
• Lithium oxide(${\mathrm{Li}}_2\mathrm{O}$) is a binary compound of Lithium and Oxygen.
• When lithium $\left(\mathrm{Li}\right)$ metal is burned in the air and combined with oxygen at temperatures above $100°C$ Lithium oxide ${\mathrm{Li}}_2\mathrm{O}$ is formed

$\underset{\mathrm{Lithium}}{4\mathrm{Li}\left(\mathrm{s}\right)}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\underset{∆}{\to }\underset{\mathrm{Lithium}\mathrm{oxide}}{2{\mathrm{Li}}_2\mathrm{O}\left(\mathrm{s}\right).}$

• It can be used as a coolant in a nuclear reactor.

Therefore, the Binary compound that contains Lithium and oxygen is Lithium oxide ${\mathrm{Li}}_2\mathrm{O}$.
