Why can the bright-line spectrum of an element be used to identify an element?
The bright-line spectrum of an element is unique because it consists of specific wavelengths corresponding to the energy levels of electrons transitioning in that element's atoms. Since each element has a distinct arrangement of electrons, the pattern of lines in its spectrum is like a fingerprint, allowing scientists to identify the element based on the specific wavelengths present in the spectrum.
What does the term bright line spectrum mean?
A bright line spectrum refers to the pattern of distinct and bright lines of different colors that are produced when an element is excited and emits light. Each element has a unique bright line spectrum that can be used to identify the element through spectroscopy.
Which element did Bohr study the line emission spectrum of?
Niels Bohr studied the emission lines of Hydrogen.
The bright-line spectrum produced by the excited atoms of an element contains wavelengths that are?
specific to that element and correspond to the energy levels of the electrons transitioning between orbitals. The wavelengths in the bright-line spectrum are unique for each element, allowing scientists to identify elements based on their spectral lines.
Is the spacing between the lines in the spectrum of an element constant or does it vary?
The spacing between the lines in the spectrum of an element are constant. This is called the emission spectrum of an element. Each element has a unique emission spectra that will be the same each time.

Element named after brilliant indigo line in its spectrum?
Indium

How is the spectrum for an element similar to a person's fingerprint?
Both the spectrum of an element and a person's fingerprint are unique identifiers that can be used for identification purposes. Each element has its own unique spectral lines that can be used to identify it, much like how a person's fingerprint is unique to them. These characteristics make both the spectrum of an element and a person's fingerprint valuable tools for identification.
What made William Crookes popular?
His most important discovery was that of the element thallium, which was previously unknown element with a bright green emission line in its spectrum. He also was the first person to discover helium.
Which element did Bohr study the line emission spectrum of?
Niels Bohr studied the emission lines of Hydrogen.
Why line spectrum is called finger print spectrum?
It is unique to a specific atom. The emission spectrum of sodium, for example, has two characteristic lines close together in the yellow part of the spectrum, which cannot be found in any other atom. Each line in a spectrum relates to a change in electron state or level.
Why a spectrum of an element is called fingerprint?
The spectrum of an element is called a fingerprint because it is unique to that element and can be used to identify it. Each element produces a distinct pattern of lines or bands in its spectrum, allowing scientists to determine the presence of specific elements in a sample by comparing its spectrum to known standards.
What element derived it name from the color of a spectrum line?
I suppose that you think to caesium (Cs).
Why would the absorption spectrum of each element have lines in the same places as in its emission spectrum?
The absorption spectrum of an element have lines in the same places as in its emission spectrum because each line in the emission spectrum corresponds to a specific transition of electrons between energy levels. When light is absorbed by the element, electrons move from lower energy levels to higher ones, creating the same lines in the absorption spectrum as the emission spectrum. The frequencies of light absorbed and emitted are the same for a specific element, resulting in matching lines.
The bright-line spectrum produced by the excited atoms of an element contains wavelengths that are?
specific to that element and correspond to the energy levels of the electrons transitioning between orbitals. The wavelengths in the bright-line spectrum are unique for each element, allowing scientists to identify elements based on their spectral lines.
How did Sir Norman Lockyer discover helium?
Sir Norman Lockyer discovered helium in 1868 in the spectrum of the sun during a solar eclipse. He noticed a yellow line in the sun's spectrum that did not correspond to any known element at the time, leading to the discovery of the new element helium.
