Mr. Neil Chipman Calculating the Atomic Mass for Different Candium Isotopes
Objective:
In this experiment I will be discovering the atomic weight of Candium isotopes. By doing this experiment, it helps us to know how to calculate the relative abundance and atomic mass of each Candium isotopes without having to use the spectrometer. This lab will achieve my understanding of isotopes and why it has different masses but same number of protons due to different numbers of neutrons in the nuclei. From this lab, I expect that we will be able to separate the candy, and be able to find the atomic mass by weighing the candy and finding the mass of it.
Procedure:
The materials needed for this experiment include: 3 different types of candies (M&Ms, Mentos, and My Mint), paper and pencil for recording data, and a digital balance in grams. The following discussions will be showing the steps for the procedure. The first step is to sort the 3 different types of candies (atoms) into 3 different isotopes. Secondly, we have to count all the atoms of each isotope and record the numbers
