Exploring Reactivity & Periodicity
Exploring Reactivity & Periodicity The question we were trying to answer was "Is reactivity a periodic property?" The reason we were trying to answer this question was to determine if reactivity is a periodic or quasi-periodic property. During our investigation we were given sodium(Na), magnesium(Mg), potassium(K), copper(Cu), and calcium(Ca). We put Na, Mg in two separate beakers and put K, Cu, and Ca in three separate test tubes. Each beaker/test tube was filled with distilled water.After we let each metal sit in the DI water for a few seconds we put a drop of phenolpthalein into each one and observed the reactions each one produced. Claim: Reactivity is a periodic property Evidence: Sodium : Color change, sizzles across the water. (2) Potassium : Sparked, smoked and fizzed. (1) Calcium : Fizzed, made bubbles in the test tube, and produced heat. (3) Magnesium : Fizzed, changed color. (4) Copper : Nothing. (5) Reasoni
