The Nature of Chemical Bonds: How Electronegativity Shapes Them

The video tutorial explains the two main types of chemical bonds: ionic and covalent. Ionic bonds form through the transfer of valence electrons, while covalent bonds form through the sharing of electrons. The nature of the bond between two atoms is determined by the difference in their electronegativities. If the difference is greater than 1.7, an ionic bond is likely, as seen in sodium chloride. If the difference is zero, a covalent bond forms, as electrons are shared equally. The video also provides examples and diagrams to illustrate these concepts.

Provide an example of an ionic compound and explain why it is considered ionic.

What occurs when the electronegativity difference between two atoms is zero?
