2. Alma, the chemistry technician, was working in the lab and discovered a potentially new element which he named Doctokumarium. Doctokumarium is thought to have 119 protons. There were three isotopes found in nature with the respective abundance and atomic mass units 72.3 % and 303.9275 amu; 3.1% and 301.272121 amu; and 24.6% and 298.773216 amu. A. Calculate the atomic mass of this potential element. B. How many protons, neutrons, and electrons does Doctohenrium have? C. Write the expected electron configuration.

3) Atmospheric argon is a mixture of three stable isotopes 36Ar, 38Ar, and 40Ar. Use the information below to determine the atomic mass and natural abundance of 40Ar. The atomic weight of argon is 39.948 u. Argon-36 35.967545 u 0.337% Argon-38 37.96732 u 0.063% Argon-40 ? ?
An unmanned space shuttle mission brings samples back to Earth from Mars. Working with samples from mars, you discover that the isotope abundances on Mars are different from on Earth. You are tasked with calculating the average atomic mass (weight) of nitrogen that exists naturally on Mars. You find that the abundance of nitrogen-15 (atomic mass of 15.000 amu) on Mars is 11.639%, and the rest of the nitrogen (abundance = 100% - 11.639%) is nitrogen-14 (atomic mass 14.003 amu). Using that information, what is the average atomic mass (in amu) of nitrogen on Mars? (answer should have 3 decimal places - only input numbers, not "amu")

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: mass relative isotope (amu) abundance 112 Sn 90.3% 111.9 119 Sn 9.7% 118.9 Use these measurements to complete the entry for tin in the Periodic Table that would be used on 98765 ALEKS. Round your entry for the atomic mass to 3 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. Sn
