Question- what are the identities of the unknown solutions? Why is a flame test able to be used? Evidence- Metal ion Calcium-bright orange  Barium-green/yellow Copper- green Lithium-red Potassium-orange Sodium-yellow/orange Strontium-red/orange Unknown #1- light orange Unknown #2-red/Orange Unknown #3/green/yellow Unknown #4-bright orange  We used our evidence of the unknown metals and compared that to the unknown metals and determined that:   The unknowns were the same shade as the knowns and we incorporated that into finding the answer , although there was some colors we could tell apart based on the shades themselves. The flame test is able to differentiate the amount of electrons which is important because when energy is absorbed by the electron it gets excited and then drops which causes the color of light to appear 

1. Recently we have been talking about the development of the periodic table and how it works, the different families, groups etc, we are learning how to better understand and read the periodic table 2. Recently I have learned that the periodic table is divided up into 4 blocks s,d,p, f  and what all of these blocks represent 3. I will continue to study my notes and create flash cards to help better understand what we are working on

1. Recently we have completed our atomic structure and electromagnetic radiation explore lab 2.  Recently we have learned about certain identities of chemicals, emissions, and worked with solutions 3. I plan to created flash cards and practice est to better help me understand the work and to prepare for tests

1. Recently we have been learning more about the periodic table and we have most recently done our chemical bonding lab swing how certain metals react in water and other substances. 2.reventlywe have learned the composition of the periodic table, balance electrons, noble gasses etc. 3. To better prepare myself I plan on creating flash cards , studying my notes and testing myself over what we do in class

1) Recently we have been diving more and more into the period table conducting labs on reactivity of elements. 2) recently I have learned how to label the periodic table, I have learned about alkali metals as well as alkali earth metals, as well as the development of the period table 3) I am planning to continue using flash cards and quizzing myself on material we’ve taken notes on to prepare myself for land and tests

Guiding Question- is reactivity a periodic property? During the investigation I watched 2 YouTube videos. Both videos showed various alkali metals and their reactions when they were dropped in water. Claim- reactivity is a periodic proper due to the reactions after the experiment was conducted. In the first video both metals created an immense amount of energy after the metals absorbed into the water creating an explosion or burst of energy In the second video both metals didn’t create as big of a reaction but both metals fizzed up upon impact and by led releasing a gas. I would expect copper to be less reactive due to its structure I feel like it would creat a noticeable reaction. Magnesium on the other hand I believe will create the same or even a better reaction such as the alkali metals used in the videos.

Recently I have done extensive practice and research on atoms and isotopes in PHET simulators to better my understanding of what we are doing in class . I have learned about the periodic table, what determines if an atom is negatively charged or positively charged, we’ve learned about ions , how to calculate mass I will crest flash card to help me understand what element is what, & I will solve problems relating to finding the mass
