Unit 8: Chemical Bonding Why and how do atoms combine to form compounds?
In this unit, we will draw Lewis structures to describe bonding and discuss several models to describe chemical bonding.
As we learn to describe the arrangements of electrons in atoms, we will be ready to relate element reactivity to electron configurations.
We will also discuss explore the regular and repeating trends in the properties of the elements.
The carbon-14 it contained at the time of death decays over a long period of time.
By measuring the amount of carbon-14 left in dead organic material the approximate time since it died can be worked out.
This will include exceptional electron configurations, typical ions formed by the elements, and Lewis dot structures to represent those most important electrons, the valence electrons.
