1)The question we were trying to answer if  reactivity is a periodic property . 2)What we did for our investigation is we got certain elements and put them in regular water to see the reaction. Since water is very simple, it made sense to put the elements in it to watch the results. 3)My claim was 'Yes, reactivity is a periodic property.' My evidence was what the element was, and what we matched what happend when it touched the water. (Highest Reactivity to Low) ----Potassium | It generated a pink flame and fizzed and moved around. ----Sodium | Fizzed and spinned around. ----Calcium | Bubbled and fizzed. ----Magnesium | Nothing when in water and turned pink when heated. ----Copper | Nothing even when heated My reasoning was 'Potassium was more reactive than Sodium, because Potassium caught on fire and Sodium did not. Then Calcium didn't moved around but fizzed like Sodium. Then Magnesium had nothing to do with the water by itself intill put in heat, and Copper

1)The tasks I have completed were finding if reactivity of an element shows a periodic property. 2)I have learned how to find a certain element from its groups, column, and families. 3)I plan on noting it better so I can find the valance and groups and such much faster. In a way I can remember better.

1) The tasks I have completed recently is doing electron configurations and orbital diagrams and learning about them. 2) I have learned that a easy way of finding the orbital diagram for a element is to look at it's row, block, and column. Getting it's final electrons and then filling in the rest before it. 3) I plan on making notes and keeping track of the 3 main rules (aufbau, pauli, hund) laws for electron configuration and what they are to get a better understanding.
