Final answer:
The element can be identified using the calculation of the average atomic mass, which involves the weighted average of the isotopic masses and their given abundances. The correct percentages need to total 100% for the calculation to be accurate. The periodic table is then used to match the average atomic mass to the correct element.
Step-by-step explanation:
To identify the element based on its isotopes, we must refer to the process of calculating the average atomic mass, which is a weighted average based on the masses and relative abundances of all naturally occurring isotopes. The formula to calculate the average atomic mass is as follows:
Atomic mass = (% abundance of isotope 1 × mass of isotope 1) + (% abundance of isotope 2 × mass of isotope 2) + (% abundance of isotope 3 × mass of isotope 3)
We also know that the total percent abundances must add up to 100%. Hence, using the isotopic data provided for the element, we can proceed with the calculations. Please note that there appears to be a typo in the abundances provided, specifically with isotope 3 which has an abundance listed as 204%. This is not possible, as the sum of the abundances of all isotopes must equal 100%. This third isotope's abundance needs to be adjusted to ensure the percentages total 100% before proceeding with a calculation.
Once corrected, we can apply the isotope abundances and masses to the formula to calculate the element's average atomic mass. This information, along with a periodic table, can then be used to identify the element in question.
The process of calculating an element's average atomic mass is similar to exercises cited from the referenced materials, where similar calculations are performed for different elements and their isotopes.
