Now that you understand much more regarding atomic structure, let’s look at chemical bonds. A chemical bond can be defined as an attractive force between two or more atoms, and they allow us to bring individual atoms and elements together to form more complex molecules and compounds such as Oz, CO2, H2O, NaCl, HCI, CH1206, etc. In the space below, name, define, and describe the three major types of chemical bonds found in the human body. . In each figure below, identify the type of chemical bond represented and explain how it is formed. 3p 9 p 4N 10 N Chemical Bond: How is it formed?
