3 question blog
The tasks I have completed lately include the flipped 3.2 and 3.3 notes and also the Electron configuration POGIL. Recently, I have learned how to calculate wavelength, light, and frequency as well as how to do electron configurations based off Pauli's, Huns, and Aufban's rules and principles. According to Pauli's rule, no two electrons in the same atom can have the same energy. Hund's rule states that electrons can not double up in an orbital until it's necessary. Aufban's principle states that electrons have a specific order. Next, I plan on completing the Ch4 practice questions and take the chapter 3 test.

Flame test lab
1. The elements can be distinguished based off the color of the flame. My results showed that Lithium (Li) was red, Sodium (Na) was orange, Potassium (K) was lavender, Calcium (Ca) was a red orange, Strontium (Sr) was a lighter red, Barium (Ba) was yellow, and Copper (Cu) was green.
2. My group and I were able to identify the unknowns. Unknown #1 was calcium. Unknown #2 was lithium. We identified these based off the color of the flame that was shown while it burned.
3. Cesium was not an element that was used because none of the colors in the second clip resembled the color of cesium.
4. The element loses energy as it is heated and put into the fire. The flame gains energy from the color the element made as it burned in the flame.

3 Question Blog
The tasks I have completed lately include the isotope abundance lab, the notes over the structure of the atom and the history behind it. Also, the unit 2 test. Recently, I've learned how to calculate the average atomic mass and how to differentiate the charges of electrons, protons, and neutrons. Electrons have a negative charge, protons have a positive charge, and neutrons have no charge. I've also learned how to count subatomic particles and nucleons. Also, how to identify everything within the elements including the atomic number, the mass number and so forth. Next I am planning to complete the placement #1 and the electron JiTT assignments.
