Question

State the type of bond formed, and draw Lewis structure of calcium oxide.

Answer 1

An electrovalent or Ionic bond is formed.

Lewis structure of CaO (calcium oxide)

\[\ce{\underset{2, 8, 8, 2}{Ca}+\underset{2, 6}{\underset{\bullet\bullet}{\overset{\bullet\bullet}{\mathbf{O}^{\bullet}_{\bullet}}}}-> Ca^{2+} [^\bullet_\bullet\phantom{.}\underset{\bullet\bullet}{\overset{\bullet\bullet}{\mathbf{O}}}\phantom{.}^\bullet_\bullet]^{2-}}\]

or 

\[\ce{\underset{2, 8}{CaO}}\]
