Intro to Chemistry

Sodium Calcium Lithium Start color for all elements All elements total  Aluminum and Magnesium Analysis - From this lab I learned that different elements have different reactions when placed in an acidic solution. Sodium and Lithium reacted the fastest quickly changing the color from an acid which is red to a base which is the color blue. The other 2 elements, Magnesium and Calcium took much longer but eventually turned the red liquid to blue. Aluminum never turned from red to blue.  What causes this reaction is when an element is placed in the acidic solution causing it to loose one of its valence electrons. What went wrong - first the lab took a very long time to actually record all the results a total of three days. Second the lab was very dangerous. Third there was unmeasured amounts of each element throwing off some of the accuracy.

The unknown mendelian belongs in the third row and 15th group lying along where the element phosphorus is placed. Questions    Analysis:  Mendelians represent a specific element upon the periodic table. Amount/ type of fingers, hair, clothing, body shape, and arms gives properties of different elements.  How these factors actually identify an element is explained to the right-->
