Question

An element is placed in 2nd Group and 3rd Period of the Periodic Table and burns in presence of oxygen to form a basic oxide. (e) Draw the electron dot structure for the formation of this oxide

Answer 1

Oxide formation

• When magnesium is burnt in the air, the formation of Magnesium oxide takes place.
• The reaction of Mg in presence of air is as follows:-
• $$\begin{gathered} 2\mathrm{Mg}\left(\mathrm{s}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to 2\mathrm{MgO}\left(\mathrm{s}\right) \\ \mathrm{Magnesium}\mathrm{Oxygen}\left(\mathrm{Air}\right)\mathrm{Magnesium}\mathrm{oxide} \end{gathered}$$

Electron dot structure of Magnesium oxide
