CHEMISTRY: Can you believe atoms are that small – and the nucleus even waaaaaay smaller! Here’s another picture of atoms from the IBM Almaden Research Center. These are iron atoms on top of copper. Being able to move atoms around like this was a giant leap in the field of nanotechnology! (Sorry about that, bad pun! π ) Here’s the lecture from Friday on atomic number and isotopes. It’s the last lecture for this chapter – and for this year!!
What did you think about Lise Meitner’s story? Amazing, huh? How are you doing on writing nuclear symbols? Also make sure you can use them to determine the number of protons, neutrons, electrons, etc. And now you’ve finally got the formula for average atomic mass. Use it to do the problems tonight.
Did you get a copy of the Carbon Isotope Mini-Project? Holler if you have any questions? Have a great weekend!
This is a lot of material to cover!I will definitely be at the next help session!!
I think I’m gonna need another help session.
Wesley – Sure! Remind me in class and we’ll set one up!
Beh, kinda sad that I had to miss today. I wish I could’ve been here for a better understanding of the lesson. Though, I’m grateful
For the vodcast. They’re very helpful and I’ll be sure to watch before class on Monday so I’m not so lost.
Judy – We missed you guys! Hope you had a good time on the field trip!
Thank you for posting the videos we watched in class yesterday, Ms. Skinner!
i think i am going to need a help session soon! we covered so much! will we talk more about our project next week?
Audra – Remind me in class and we’ll set one up!
Do we have any tests or quizzes before exams?
The homework we had over the weekend was hard to understand.
hopefully ill understand this soon!! :/
Are we going to have a help session before we take the test?
this video helped alot!
For the project do we need to have the electrons on the project or just the protons and nuetrons?
Garrett – Important question! Go back and check the purpose of the project. What does it say you are supposed to make?
Are you going to give us a study guide to study for the exam?
I will be at the help session tomorrow. I think it’ll be helpful to go over what we’ve learned the morning of the test.
I liked doing the worksheet in the computer lab. It was nice to do something different.
i really hope to do well on this next test
I’m pretty sure you can do it either way but does it matter if we put the short way of writing neutron or do you want us to write neutron out?
Aidan – Either way is okay.
I have a good feeling about this test!
This test is going to be hard, but I think I’m ready!
This project has been really fun to do!
When will we get our grades for our project?
These videos will definitely help me on my study guide.
I hope to do well on the exam.
