QUESTIONS
2. Describe the path of the alpha particles through the positive "goo" in the
Plum Pudding simulation.
3. Describe the path of the alpha particles in relation to the central mass in the
Rutherford Atom simulation.
4. What effect does increasing the number of neutrons have on the paths of the
alpha particles as they approach the central mass?

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
