What is it that you are doing?

We are observing the different colors that each ion makes when placed in the bunsen burner.

Why does this phenomenon happen?

17fosterrc238 — 2013-10-18 20:33:09 UTC

The electrons in an ion jump from the ground state to the excited state. When the electrons go back down to the ground state, it causes a change in color.

How did you do it?

After the flame turned to a full blue color, we inserted the sticks that were soaked in the chemicals and watched what color the flame turned out to be.

What happened in your experiment?

17fosterrc238 — 2013-10-18 20:33:56 UTC

Every element that we placed in the bunsen burner turned the flame into a different color.

How did you determine your unknown?

We determined our unknown element by comparing it to the other flames to see which color it closely resembled.
