Exploring Atomic Structure & Electromagnetic Radiation    The question we were trying to answer was "What are the identities of the unknown solutions?" The reason we were trying to answer this question was to get a better understanding of the unique colors each one emits. During our investigation we had seven wood sticks soaked in the solutions CaCl, BaCl, CuCl, LiCl, KCl, NaCl, SrCl, and four soaked in a unknown solution. We took each solution soaked stick, tested them in a flame test and observed the colors each one produced.    Claim: Unknown 1: Potassium, Unknown 2: Lithium, Unknown 3: Barium, Unknown 4: Sodium    Evidence:    Reasoning: Our reasoning is that 1, 3, and 4 are different shades of orange and green. Ion 2 matched the color lithium produced when it was put under fire. A flame test is used to determine the metal ion based on the color it produces. It produces color because the electrons become excited by the energy of the flame, because

Exploring Isotopes & Average Atomic Mass   The question we were trying to answer was "What is the atomic mass of beanium". During our investigation we separated the three different types of beanium, counted them, and then took the mass of each type in groups. We weighed it this way because each bean is not same, but we want them to be. We got the mass of each group and divided it by the number of beans to get the mass of an individual bean.   Our claim was that the atomic mass of beanium is .42g. Evidence:                                                   =.42g   Our reasoning is we took the average mass of bean and multiplied it by the abundance(percent) and added each one than divided by 100. for this we got the atomic mass of beanium as .42g. We took the average mass of the beans because we want them to weigh the same. We took the percent because there isn't the same amount of beans per group.
