Work Step by Step

$^{6}Li$ has 3 protons. Since the isotope has 18 times as many protons, the isotope must have 54 protons. Therefore, the isotope must be an isotope of Xenon. $^{12}C$ has 12 nucleons. Since the isotope is 11 times as heavy as $^{12}C$, the isotope must have 132 nucleons. The isotope is: $^{132}Xe$
