Unit 2 ( Isotopes conundrum Set 2-2 1. Which of the spargon-time activity ar isotopes of element X, with nuclear offspring of 9: [pic],[pic],[pic], and [pic]. 2. For to from each one maven of the following isotopes, write the nuclear symbols: a. Cu-63, Cu 65 b. C-12, C-14 c. Mg-24, Mg-25, Mg-26 d. Ne-20, Ne-21, Ne-22 3. Verify that the atomic draw of magnesium is 24.31 amu, presumption the following information: [pic], circuit = 23.985042 amu; share copiousness = 78.99% [pic], throng = 24.985837 amu; part abundance = 10.00% [pic], rush = 25.982593 amu; percentage abundance = 11.01% 4. of course occurring neon is a intermixture of ternary isotopes with the following mob and abundances: rush NumberAtomic Mass% Abundance 2019.9990.51 2120.99 0.27 2221.99 9.22 propose the atomic peck of by nature occurring neon. 5. Nitrogen has twain of course occurring isotopes N-14 and N-15, whose atomic dregs of the people are 14.0031 and 15.00001, respectively. The atomic mass of newton is 14.0067. What are the percentages of each of the isotopes? 6. crap has cardinal stable isotopes,[pic]and [pic], with masses of 62.939598 amu and 64.927793 amu, respectively.
guide the percent abundances of these isotopes of copper. 7. atomic follow 24 has four naturally occurring isotopes: atomic number 24 50 (4.35% at 49.946 amu) chromium 52 (83.79% at 51.941 amu) chromium 53 (9.50% at 52.941 amu), and chromium 54 (2.36% at 53.939 amu) Calculate the average atomic mass of chromium. 8. There are two naturally occurring isotopes of atomic number 35: Br-79 (78.918 amu) and Br-81 (80.916 amu. What is the percentage of each isotope? 9. There are two isotope of fin: V-50 (49.947 amu) and V-51 (50.944 amu). What is the percent abundance of each isotope?If you want to let down a full essay, high society it on our website:
