Antimony has many uses, including infrared devices and as part of an alloy in lead storage batteries. The element has two naturally occurring isotopes, one with mass 120.904 amu, the other with mass 122.904 amu. A (a) Enter the X notation for each isotope. antimony–121 antimony–123 (b) The atomic mass of antimony is 121.8 amu. Use this value to calculate the percent abundance of each isotope. 55.2 % antimony–121 44.8 % antimony-123
