How can we write the correct symbol with the mass number and atomic number?
Finding atomic mass from isotope mass and natural abundance A robot spacecraft returned samples from the planetesimal 98765 ALEKS, located in the outer Solar System. Mass-spectroscopic analysis produced the following data on the isotopes of tin in these samples: isotope 119 S Sn 118 Sn Sn mass relative (amu) abundance 118.9 93.3% Explanation 117.9 Use these measurements to complete the entry for tin in the Periodic Table that would be used on 98765 ALEKS. Be sure your answers have the correct number of significant digits. Caution: your correct answer will have the same format but not necessarily the same numbers as the entry for tin in the Periodic Table we use here on Earth. 6.7% X Check 3 ? O ol Ar ve Graw Hill LLC.
