What This Document Is
This document outlines the third laboratory assignment (Lab 3) for CHM 2045, General Chemistry I at Florida SouthWestern State College. It details an at-home experiment focusing on the concepts of isotopes and ions, and how these relate to flame colors of salts. This assignment is designed to be completed individually as part of the course requirements.
Why This Document Matters
This lab assignment is crucial for students enrolled in General Chemistry I. Successful completion demonstrates understanding of fundamental atomic structure concepts, including isotopic abundance and the relationship between electron configuration and observable phenomena like flame tests. It’s used to reinforce theoretical knowledge with a hands-on, albeit simulated, experimental approach.
Common Limitations or Challenges
This document provides the experimental framework and background information, but does *not* provide completed data, calculations, or analysis. Students are expected to perform the experiments (using M&Ms) and calculations independently.
What This Document Provides
The full document includes: background information on isotopes and atomic mass, a detailed procedure for determining the atomic mass of a hypothetical element ("Mm") using colored candies, an explanation of the Planetary and Bohr models of the atom, and instructions for relating atomic structure to observed flame colors. This preview *does not* include the data tables for recording M&M isotope abundance, the calculations required to determine atomic mass, or the specific questions to be answered in the lab report.
