A chemical bond is the result of an attraction between atoms or ions. The types of bonds that a molecule contains will determine its physical properties, such as melting point, hardness, electrical and thermal conductivity, and solubility. How do chemical bonds occur? As we mentioned before, only the outermost, or valence,

Both are made of nothing but carbon atoms. The answer lies in the chemical bonds among those atoms and how they give rise to different structures. In this quiz, explore what chemical bonding is, and how it accounts for the properties.

5 GENERAL LEARNER OUTCOMES Students will: 1. Apply various models, evidence and theory to explain the structure, chemical bonding and properties of.

In general, strong chemical bonding is associated with the sharing or transfer of electrons between the participating atoms. The atoms in molecules, crystals, metals and diatomic gases—indeed most of the physical environment around us —are held together by chemical bonds, which dictate the structure and the bulk.
