Use the formal charge arguments to rationalize why BF3 would not follow the octet rule
Monday, February 1, 2016 Chapter 2 cont. charge on e = 1.609 x 10 -19c calculated mass on e = 9.11 x 10 -31kg Millikan Oil Drop experiment - Observed charges on oil droplets produced by x-rays with voltage on and voltage off. Voltage on-> droplets with negative charge will fall more slowly or even rise. - There must be another particle to neutralize atom. Proton • Radioactive material discoveries - gamma γ: high energy photons - alpha α: (helium nucleus) heavy emission - beta β: (free electrons) negative emission • Rutherford (1871-1937) Gold Foil experiment - tests “plum-pudding” model and concludes with his “nuclear” model - Noble Prize in Chemistry 1908 α Bombardment of Metal Foil: about 1
