Chemistry 4-23-21 Radioactive Decay

CHEMISTRY: Today has been all about arrows for some reason – well, sideways arrow! 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! Need extra help? Help session Friday morning, 7:20ish A.M.

Be sure and bring a calculator Monday – we’ll tackle half life problems! 🙂
