Characteristics of Chemical Bonds

In general, strong chemical bonding comes with the sharing or transfer of electrons between the participating atoms. The atoms in molecules, crystals, metals and diatomic gases are held together by chemical bonds. There are two types of bonds; covalent and ionic. Covalent bonds form when atoms share electrons.

Compare Contrast and Debate

Background: While most text books and other sources categorize chemical bonds into a handful of “types” – in practice, the bonds formed between substances vary depending on the specific substances forming the bond. Some might argue that rather than just a few types of bonds – each bond between unique substances has some unique aspects about the bond itself.

  • Position A: There is value in categorizing “like-kind” bonds into broad groups.
  • Position B: A better way of learning about bonds would be to treat every combination of bonds as unique, without using a broad category.
