Chemistry Review

     In class today we did a review of basic chemistry, such as the octet rule, ionic and covalent bonding, and the lewis dot structure. I did a Making Molecular Models worksheet with a partner which emphasized atomic bonding and the octet rule. The octet rule is a rule that states that elements all prefer to bond in a way that can allow them to have eight electrons in their outermost shell. The electrons in this outer shell are known as an elements "valence electrons" and are the electrons that are taken away or are added to during bonding. We also reviewed polar and non polar bonds, and had to name which compounds are polar, for example H2O is polar, but H2 is not. Basic chemistry is important to learning biology because everything is made of chemical compounds, and understanding those will lead to a deeper understanding of Biology.
