A sample of lithium consists of 400 atoms. 30 atoms are the isotope Lithium-6 (6.015 amu) and 370 are Lithium-7 (7.016 amu). Which student correctly calculated the correct average atomic mass and why? Student 1 calculated the average atomic mass as 6.94 amu. Student 1 determined the percent abundance for each isotope and then multiplied the percent abundance by the average atomic mass of its isotope and took the sum. Student 2 calculated the average atomic mass as 6.52 amu. Student 2 took the average of the mass of the two isotopes of lithium. Student 3 calculated the average atomic mass as 1.06 amu. Student 3 took the sum of the average atomic masses of the isotopes and multiplied by the ratio of lithium-6 to lithium-7. Student 4 calculated the average mass as 13.0 amu. Student 4 added the mass of the two isotopes.
11. Identify as true (T) or false (F): Minerals separating from flowing water as stony deposits represents a physical change. A pure substance may be made of a single element or of a single compound. Atoms of different elements must have different numbers of protons in their nuclei. The smallest piece we can separate from an atomic substance physically is an atom.

1. Marie Curie was a Polish scientist that specialized in chemistry and physics. She wanted to understand how X-rays worked and noticed in her studies that the element, Uranium, gave off rays that could be measured but did not know what the rays were. She assumed that the rays came from the uranium itself instead of through different molecules interacting with each other. To study the rays, she used an instrument, called an electrometer, that studied the electricity that the rays passed through the air. Through this she was able to discover that the more uranium atoms there were in a compound, the stronger the rays that came off of it. She used this discovery to test other minerals that emitted more rays than Uranium, and discovered the elements Thorium, Polonium and Radium. Through her discoveries of these elements, scientists were able to find the structure of the atom and even how the rays can be used to fight cancer. What was Marie Curie’s observation? 2.
