QUESTION Bromine has two isotopes, 79Br and 81Br. To find out the isotopic abundance of each bromine isotope, a sample of Br, was injected to a mass spectrometer which subsequently released the spectra shown below. From each spectrum height was measured and tabulated. Explain why the peak height at the mass number 160 is twice as high as the peak height at the mass number 158 or 162. DATA Mass Number Peak height, cm 79 4.12 81 4.12 158 3.34 160 6.68 162 3.34 79 81 158 160 162 MASS, amu Relative Abundance
