Is to perform and observe the flame tests of some alkali and alkaline earth metal  ions. The Normal configuration of the electrons about the atom or the ion of an  element is called “the ground state”. The electrons of this stable particle are at  their lowest possible energy level. When they are heated however, some of the  electrons leave their ground state and become excited. They become excited by  absorbing heat energy, albeit only momentarily and quickly return to their ground  state. As they return to their ground state they release the heat energy in the form  of electromagnetic energy. Some of this energy is visible in the electromagnetic  spectrum and we can see the visible light possessing color. The color of the light  released can confirm the identity of an element. This is called a flame test and

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
