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.
