Chemistry 1-17-19 Radioactive Decay & Half Life

CHEMISTRY: Today we finished talking about the properties of radioactive nuclides, then it was all about arrows and where to put them! 🙂

HOMEWORK UPDATE FOR THURSDAY (Due Friday): Pg. 672 – 674; 11 – 21, 30 – 33, 40, 42

So how are you doing with the nuclear equations? Feeling better about them now that you know what side of the arrow to put the particle on? Also, make sure you memorize the nuclear symbols for alpha particles, beta particles (electrons), positrons, neutrons, and protons – those are just as important as the arrow!

Great job today on our first look at half life! We’ll tackle them full force in class tomorrow. Bring your calculator! 🙂
