introduction: the energy levels in atoms and ions are the key to the Skip to document Ask an Expert Sign inRegister Sign inRegister Home Ask an ExpertNew My Library Discovery Institutions University of the People Harvard University Maryville University In the flame test you saw a single color as the excited atoms released the energy they gained. The manipulated variable was the element being tested. These they will place into a flame in order to observe the colors produced. Gas-discharge tubes for hydrogen, helium and mercury are set up at the front bench. As many elements will still produce distinctive colors under such conditions, simple flame tests can be used to identify these elements. For the same radio station, calculate the energy (E) in kilojoules, kJ. It can be in the form of light, an electric discharge, or heat. Digital Flame Take a look at Lab Reply Key. The result is called a line emission spectrum, and can serve as a fingerprint of the element to which the atoms belong. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Utilizing your knowledge, establish the metallic ion in your unknown resolution. From your results, you will draw conclusions about the colors released from heated metal ions. Not all metal ions give flame colors.

Perform a flame test to identify the characteristic color of metal ions. The ground state is the state in which the electrons in Different elements emit different emission spectra when they are excited because each type of element has a Ultraviolet, Visible, Infrared, Microwave, Radio ] Virtual Labs > Contact Publications . For example, the line spectra shown below for the elements helium and carbon are clearly quite different (colors can be seen in the PDF document on-line).
