Two of the isotopes of lithium are represented as 36Li^{6}_{3}\text{Li}36​Li and 37Li^{7}_{3}\text{Li}37​Li. The relative atomic mass (ArA_rAr​) of lithium is 6.946.946.94. Which statement is true about the abundance of each isotope in a sample of lithium?

  • Statement 1: There are fewer 36Li^{6}_{3}\text{Li}36​Li atoms than 37Li^{7}_{3}\text{Li}37​Li atoms.
  • Statement 2: There are more 36Li^{6}_{3}\text{Li}36​Li atoms than 37Li^{7}_{3}\text{Li}37​Li atoms.
  • Statement 3: There are equal numbers of 36Li^{6}_{3}\text{Li}36​Li and 37Li^{7}_{3}\text{Li}37​Li atoms.
