Question

Define the term oxides.

Answer 1

1. Oxides are compounds in which an oxygen atom is attached to one or more elements.
2. For Example: sodium oxide(Na₂O), calcium oxide(CaO), Aluminium oxide(Al₂O₃), and many more.
3. Based on acid-base characteristics of oxides they are categorized as acidic, basic, or neutral oxides.

For example: $$\begin{gathered} \mathrm{Na}\left(\mathrm{s}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to \mathrm{NaO}\left(\mathrm{s}\right) \\ \left(\mathrm{sodium}\right)\left(\mathrm{oxygen}\right)(\mathrm{sodium}\mathrm{oxide}) \end{gathered}$$
