Chemistry for Biology Students

Even though this post is from quite a while ago, I thought I would link to it because I could have just as easily written it today…

The letstalkaboutscience blog posted this great infographic illustrating the abundance of each of the elements in the universe, the oceans, etc. I’ve brought that here – click to enlarge and explore in greater detail.


This week, we talked about the various bonds that atoms engage in to satisfy the octet rule. I also found this great, simple illustration of Na and Cl forming ions and bonding through Imagetheir difference in charge.

¬†On Tuesday we’ll finish up discussing bonding and talk about the four basic molecules of life (proteins, nucleic acids, fats and carbohydrates). Then we’ll finish up with this brief overview of chemistry by talking about how it fits into the big picture.
