Calcium Carbonate and Ionic Bonds

This video tutorial explains how to write the Lewis structure for calcium carbonate (CaCO3). It covers the ionic nature of the compound, detailing how calcium, a metal, transfers its electrons to the non-metal carbonate ion. The video describes the charges involved, with calcium having a 2+ charge and the carbonate ion having a 2- charge, and how these charges lead to the formation of an ionic bond. The tutorial also provides a visual representation of the Lewis structure and offers a link for a more detailed explanation.

Why do we use brackets in the Lewis structure of the carbonate ion?

• To highlight shared electrons

• To show the ion is stable

• To indicate a positive charge

• To denote the negative charge

What allows the formation of the ionic bond in calcium carbonate?

• The transfer of electrons from carbonate to calcium

• The attraction between opposite charges

• The sharing of electrons between calcium and carbonate

• The presence of a covalent bond

What happens to calcium's valence electrons in calcium carbonate?

• They remain with calcium

• They are transferred to carbonate

• They are shared with carbonate

• They are lost to the environment

What is the result of the opposite charges in calcium carbonate?

• They neutralize each other

• They attract and form an ionic bond

• They repel each other

• They form a covalent bond
