Helpful links

As I'm studying, i have been placing links, pictures, and videos that may help others for this upcoming Unit test here:
http://www.chem4kids.com/files/atom_structure.html - here is an easy outline of the atom's structure

https://chemistry.osu.edu/~woodward/ch121/ch2_atoms.htm - table and site that will go more in depth with atomic structure

http://vignette2.wikia.nocookie.net/schools/images/0/0b/Chart.JPG/revision/latest?cb=20060611033958 - here is a picture that will hopefully help outline most of the aspects to radioactive decay

here is a useful link and video that will help outline and explain the different types of decay

http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch23/modes.php another link to help with radioactive decay

https://www.khanacademy.org/science/chemistry/atomic-structure-and-properties -khan academy is a excellent site to explore the atom in different ways and videos

https://en.wikipedia.org/wiki/Plum_pudding_model i had trouble with the difference between Johnson's model and the rest, so i hope this link is helpful


I hope these links, pictures, and videos have helped you study just like they helped me.

Post- Weekly quiz #1

We took the first quiz of the atomic structure and radioactivity today and i felt like i knew the majority of the content. I realized afterwords that i did not calculate the average atomic mass correctly, but i now reviewed the equation and have corrected my mistake for the unit test. Otherwise, I have understood this unit and haven't had very many problems so far.

Beanium Lab


Today we did a lab replacing isotopes and atoms with beans. This lab helped me understand the total average mass equation that we learned yesterday because I was physically working out the problem and visualizing the beans as the isotopes. I also learned that the total average mass of the four isotopes should be closest to the more abundant isotopes mass.

Mass of Subatomic Particles

Today the notes we learned about were more based on the equation of determining either the percent abundance or average mass, which has the equation: [(mass)(%)]+[(mass)(%)]=total average mass. This equation is easy to understand, but i will need to do some practice some problems to be able to easily use the equation when need be.

First in-Class Notes

After our first in-class lecture, i am excited to begin the math part of Chemistry. I am also excited to learn about an atom in more detail to fully understand its properties and how the discovery of all of those aspects came along over time. By the end of this unit, i hope to fully understand all of the concepts through studying and reviewing what I have learned.

Pre Test

I took the pre-test last week which made me realize that i don't have an abundance of prior knowledge for this unit, but i do remember some terms such as half-life or gamma radiation from my previous science classes. I am excited to learn more throughout this unit and for this upcoming project with being able to study the stars and aspects of space.

Final, Final Thoughts about Nomenclature

Reflection on Nomenclature

I learned in the Nomenclature Unit that there are three different types of ways to name ionic compounds and covalent compounds. When naming acids, I remember "No O go hydro", so if there is oxygen in the compound, there wont be a hydro-suffix.
