Question

List the elements that form a basic oxide with oxygen.

Answer 1

Basic oxide:

• Metals by reacting with oxygen form the basic compounds of oxygen which are known as basic oxides.
• Group $1,2$ and lanthanides usually form basic compounds of oxygen when they react with Dioxygen and these compounds are usually ionic in nature.
• During the formation, these compounds release a large amount of energy during their formation.
• The group 1 element reacts with oxygen to make metal oxides which at room temperature, react with the surface of the metal and forms a white oxide, covering the surface.
• The Reactions of Group two Elements with Oxygen results in tarnish in air to form a coating of the metal oxide.
• Lanthanides tend to react with oxygen to form oxides for which the reaction at room temperature can be slow while heat can cause the reaction to happen rapidly.

The list of elements that form a basic oxide with oxygen:

• Sodium : $\underset{\left(\mathrm{Sodium}\right)}{4\mathrm{Na}\left(\mathrm{s}\right)}+\underset{\left(\mathrm{Oxygen}\right)}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\to \underset{(\mathrm{Basic}\mathrm{oxide})}{\underset{(\mathrm{Sodium}\mathrm{oxide})}{2{\mathrm{Na}}_2\mathrm{O}\left(\mathrm{s}\right)}}$
• Magnesium :$\underset{\left(\mathrm{Magnesium}\right)}{2\mathrm{Mg}\left(\mathrm{s}\right)}+\underset{\left(\mathrm{Oxygen}\right)}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\to \underset{\left(\mathrm{Basic}\mathrm{oxide}\right)}{\underset{\left(\mathrm{Magnesium}\mathrm{oxide}\right)}{2\mathrm{MgO}\left(\mathrm{s}\right)}}$
• Calcium :$\underset{\left(\mathrm{Calcium}\right)}{2\mathrm{Ca}\left(\mathrm{s}\right)}+\underset{\left(\mathrm{Oxygen}\right)}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\to \underset{\left(\mathrm{Basic}\mathrm{oxide}\right)}{\underset{\left(\mathrm{Calcium}\mathrm{oxide}\right)}{2\mathrm{CaO}\left(\mathrm{s}\right)}}$

Hence, the list of the elements that form a basic oxide with oxygen is given as: Sodium, Magnesium, Calcium, etc.
