electron energy levels caused in hydrogen cause these lines in the spectrum to be produced in this way because the wavelengths that are released when the electron move back to the ground state is specific and it varies accordingly. 2. Into which energy level are electrons dropping into to make these visible lines? The electrons are dropping back to the ground state which is the bottom most energy level to makes these visible lines. 3. What happens when the electrons drop into the 1st energy level

Ground state- normal configuration of the electrons about the atom or the ion of an element; stable particle electrons are at lowest possible energy level Excited state- when stable particles are heated to very high temperatures some of the electrons leave their ground state and become “excited”; these electrons move to higher energy levels 3. What is flame test? Why do different

Flame Test Laboratory Report Introduction The purpose of this lab is to observe and identify metallic ions‚ using flame tests. The traditional flame test originated when Robert Bunsen invented the Bunsen burner to test two new alkali metals he and his partner had discovered. “A flame test is an analytic procedure used in chemistry to detect the presence of certain elements‚ primarily metal ions‚ based on each element’s characteristic emission spectrum” (Flame Test 1). Using this test‚ an element

INTRODUCTION Flame photometry‚ also referred to as ’flame atomic emission spectrometry ’ is a quick‚ economical and simple way of detecting traces of metal ions‚ primarily Sodium‚ Potassium‚ Lithium‚ Calcium‚ and Barium‚ in a concentrated solution. The process is an extension of the principles used in a flame test‚ with the main differences having more precision in the results‚ and the use of more advanced technology. This report focuses on the theory‚ applications‚ limitations and analysis of Flame Photometry

Don’t Support Nuclear Energy These days‚ it seems like everyone is worried about how the world will meet its energy demands when we don’t have oil and natural gas. Scientists and researchers are investigating such power sources as solar energy‚ wind energy‚ and even energy new kind of energy shale gas recources . However‚ there is one energy source that I believe should not be developed anymore. In fact‚ I believe that we should stop using it as soon as possible. Even though it can provide

Flame lab test Chemistry Introduction The lab test performed was to determine characteristic colors that were produced by specific metallic ions that are shown in a flame. This happens when an electron gains energy; the electron moves from an energy level that’s farthest away and to an empty orbital close to the nucleus with higher levels‚ so one of the electrons gives off energy. A flame test is a visual test where the energy is in the form of a color change and the change can

your answer to support each position. (6 marks) Answer: 2. The emission spectrum of an unknown element contains two lines-one in the visible portion of spectrum and the other‚ ultraviolet. Based on Figure 1.1 and on what you have learned about Niels Bohr’s model of atom‚ account for the difference in energy between these lines. (3 marks) Answer: The line which is on the visible portion of spectrum is produced when electron is jumping from higher to lower energy level orbit thus releasing
