Isotopes and Decay

Chapter 7 is upon us and we have begun exploring the unique characteristics of isotopes and radioactive decay!

Below is a model of carbon -12, carbon -13 and carbon -14.  Can you spot the differences in these nuclei of the different isotopes?

(credit Leiah for their construction)

We have also talked about decay and how unstable nuclei will emit high energy particles or energy in the attempt to stabilize.  

Alpha, Beta and Gamma decay/radiation are the highlight of the popular music video above.

Remember -we will have a quiz next class on the three different types of Decay!

Chapter 6 just flew by!

It feels as though we have just come back from holidays, and already we're preparing for a test!  Chapter 6 is already over and done, so we are ready to pack it up and move along.

Here is an update from the girls in the front row of block 3:

Hey Gang,

So as you may already know there is a quest on chapter 6.1 and 6.2 happening soon, and I want you guys to be prepared! (Don't worry, you'll all do great!!) Some of the things you would want to study are the 5 types of reactions (AB equations etc...), Identify WHY it's that reaction (ex its a synthesis because there's only 2 reactants so obviously they're gonna combine into 1). Know the 4 factors affecting reactions rates, and why those are factors.

Best of luck

Test dates are:

Block B = Tuesday January 27

Block 3 = Monday January 26

**If you have made special arrangements with Ms. Logher -then those specific dates are yours**

Science 10B Tuesday Homework

Welcome back!!  I hope you're holidays were fun and you're ready to jump right back into Chemistry!  We went through chapter 6.1 today -have a look at the notes and complete the following for next class (Thursday).  Remember to write down any questions you have.

1. Complete worksheet questions (back side)
2. Create 5 unique analogies for the 5 different reaction types (remember double replacement is the same as a neutralization) to share in class
