Today in class we learned about atomic level pictures. We defined the terms:
- atom - most basic unit of matter
- molecule - group of atoms help together by a chemical bond
- element - made up of single type of atom
- compound - molecule made up of more than one kind of atom
Then we did a couple of problems from the worksheet to furthermore explain the difference of these four terms and learn to distinguish them.
In this problem we had to decide for the each of the atomic level diagrams whether they are elemets or compounds and consisting of either atoms or molecules.
Then we defined two more terms:
- pure substance - all the same
- mixture - has different kinds
To get a better understanding of what these terms we did another problem from the worksheet.
We also learned how to write formulas for atomic level pictures.
After that we practiced drawing the atomic level pictures according to the formulas that were given.
Then we had even more practice with writing the formulas and descriptions for the atomic level pictures and also drawing the atomic level pictures based on the formulas.
Once we were done with everything, we had some time to just talk to other people untill it was time to go to the fall sports assembly.
It helps alot that you put pictures in your post, it makes it much easier to understand.
