1. What is the identity of Elements 1 and 2 in the green rock? Iron and Nickle 2. In the graphs below, sketch the mass spectrum for each element; write the symbol of the isotope above each spectral line. 91.75% Abundance (%) 5.85% 2..12% 0.28% 53.9 56,9 55.9 Mass (a.m.u.) One 57.9 68.08% Abundance (%) 5.22% 463% 1.14% 0,93% Two 57.9 59.9 60.9 61.9 62.9 Mass (a.m.u.) 3. Although nickel has a higher atomic number than cobalt, nickel's atomic mass is less than that of cobalt. Why? Nickle has less neutrons than cobalt. Neutrons make up the majority of an elements weight while protons determine of the Atomic number. 4. (Optional) Is this rock a meteorite or a meteorwrong?Hint: look at the metal composition of FeNi meteorites; http://matoonitog umotl dulid/motal htm)
