To identify an unknown sample by its emission spectrum

Bohr studied the line emission spectrum of hydrogen.

No, an atomic emission spectrum is not a continuous range of colors. It consists of discrete lines of specific wavelengths corresponding to the emission of light from excited atoms when they return to lower energy levels. Each element has a unique atomic emission spectrum due to its unique arrangement of electrons.

The emission spectrum of sodium lies in the yellow region of the visible spectrum, specifically around 589 nanometers.

The emission spectrum of elements is a unique pattern of colored lines produced when an element is heated or excited. Each element has its own distinct emission spectrum, which can be used to identify the element.

No. It is not possible for two metals to have the same emission spectrum. For metals to have the same emission spectrum, they would need for their electrons to have duplicate orbitals. That would be impossible due to the exclusion principle.

The number of lines in the emission spectrum is the same as in the absorption spectrum for a given element. The difference lies in the intensity of these lines; in emission, they represent light being emitted, while in absorption, they represent light being absorbed.

White light has a continuous spectrum with all wavelengths of light present, while the atomic emission spectrum of an element consists of specific wavelengths corresponding to the energy levels of the element's electrons. The emission spectrum is unique to each element and can be used to identify the element present.

Identify elements

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.

Every element can produce an emission spectrum, if it is sufficiently heated. Of the 4 elements that you mention, neon is the most useful, in terms of its emission spectrum, and it is used in a certain type of lighting.

No.

The photosphere.

Emission spectrum: lines emitted from an atom.
Absorption spectrum: absorbed wavelengths of a molecule.

The spectrum produced when elements emit different colors when heated is called an emission spectrum. Each element has a unique emission spectrum based on the specific wavelengths of light it emits.

This would consist of several series of lines corresponding to the energies of electron transitions. They are bright lines for an emission spectrum and dark for absorbtion.

A band spectrum is an absorption or emission spectrum consisting of bands of closely-spaced lines, characteristic of polyatomic molecules.

A band spectrum is an absorption or emission spectrum consisting of bands of closely-spaced lines, characteristic of polyatomic molecules.

An absorption spectrum shows the wavelengths of light absorbed by a substance, appearing as dark lines on a bright background. An emission spectrum shows the wavelengths of light emitted by a substance, appearing as bright lines on a dark background. In other words, absorption involves light being absorbed by the substance, while emission involves light being emitted by the substance.

The emission spectrum of an element

continuous emission

The range of colors emitted by a heated atom is called its emission spectrum. Each element has a unique emission spectrum due to the specific energy levels of its electrons.

The emission spectrum of hydrogen primarily includes red, blue, and violet wavelengths of light. These correspond to specific transitions between energy levels in the hydrogen atom.

By looking at its emission spectrum and seing where the black lines are

The colors in the emission spectrum of sunlight range from violet to red. This spectrum is created by the various wavelengths of light emitted by the sun, and can be seen when sunlight is passed through a prism or diffraction grating, creating a rainbow of colors.

to identify an unknown sample by its emission spectrum

A star's emission spectrum is a unique pattern of light emitted by the star, showing distinct wavelengths or colors of light. It provides information about the star's composition, temperature, and other properties. By analyzing the emission spectrum, astronomers can learn about the chemical elements present in the star and its physical characteristics.

The emission spectrum of each element has characteristic lines for each element. Analyzing the spectrum of a star, you can figure out what elements are present, and also get an estimate on how much there is of each element. For more information, check the Wikipedia article on "emission spectrum".

Absorption spectrum is a gap in the overall spectrum. It happen when light makes an electron jump to a higher orbital and light energy is absorbed.

Emission spectrum is light emitted at particular wavelengths (where the absorption spectrum gaps are). It happens when an electron falls from a higher orbital and emits light energy in doing so.

Each chemical element has a specific emission or absorption spectrum.

Edit: The question is very mixed up, but I think I get the idea.

It's obviously an emission spectrum.

Because it is a high density gas the spectrum should be CONTINUOUS.

An emission spectrum is used to identify elements present in a sample by measuring the specific wavelengths of light emitted when the atoms are excited. This can be helpful in areas such as astronomy, chemistry, and material science for determining the composition of a substance.

The emission spectrum of barium nitrate typically includes several bands of light in the visible region, with some lines in the blue-green part of the spectrum being the most prominent. The specific wavelengths and intensities of these lines can vary depending on the experimental conditions.

The emission spectrum is the electromagnetic radiation spectrum of a particular chemical. The major ways this is observed is through special equipment designed for it, though flame emission spectroscopy is its own method, wherein burning a chemical produces a particular color of flame.

The fluorescent light emission spectrum determines the colors produced by a fluorescent light source. Different elements in the phosphor coating of the bulb emit light at specific wavelengths, which combine to create the overall color of the light. The emission spectrum influences the perceived color of the light emitted by the bulb.

It doesn't. An absorbtion spectrum is produced when it absorbs energy. An emission spectrum is produced when it lets the energy go again. The energy changes are associated with the element's electrons going up to higher energy levels and then dropping down again.

binary star systems

The hydrogen line emission spectrum was discovered by physicists Johann Balmer, Johannes Rydberg, and Niels Bohr. They observed that hydrogen gas emitted specific wavelengths of light, which formed a distinct spectrum now known as the Balmer series.

The white light emission spectrum is significant in optics and light sources because it contains all the colors of the visible spectrum. This allows for a wide range of applications, such as in color mixing, photography, and creating accurate color representations.

The Sun's wavelength of maximum energy emission falls within the visible light spectrum, specifically in the range of around 500 to 600 nanometers. This corresponds to the green to yellow part of the spectrum.

The nitrogen emission spectrum is characterized by a series of distinct lines of light that are emitted when nitrogen atoms are excited. These lines are specific to the energy levels of nitrogen atoms and can be used to identify the presence of nitrogen in a sample.

"Emission Spectrum" can mean a number of things...

Many objects emit light and they all have an emission spectrum, that is a set of wavelengths of light that they give out. The emission spectrum for an L.E.D. bulb for instance is pretty narrow, just one visible colour. The emission spectrum of a star is very wide, encompassing non-visible light as well.

It is probably these stellar emission spectra you are referring to, so I'll go on from that assumption. The fusion processes within a star (at most levels from core to surface, but mostly in the core) create most of a spectrum, but some of this light is absorbed by the outermost layers. That is why we see gaps, and molecules of certain types absorb certain parts of the spectrum, so we use the spectrum to determine composition.

We also see spectra from diffuse bodies like nebulae. These are, broadly, of 2 types, emission and absorption. Absorption spectra occur when we observe a known star through the cloud, and extra lines missing beyond what we expect of the star will be emblematic of the constituents of the cloud. Emission spectra from clouds can also occur, that is when the light falling on them is not aligned with us, what we see is several narrow bands of light, which has been absorbed and re-emitted by the cloud.

An emission spectrum of a gas in a discharge tube shows only specific wavelengths of light emitted when electrons in the gas atoms transition to lower energy levels. This produces distinct colored lines on a dark background. In contrast, a white light spectrum shows a continuous range of wavelengths across all colors of visible light due to the presence of a broad spectrum of colors.

Yes, an emission spectrum is created when a gas is heated at high pressure. The high pressure excites the gas atoms, causing them to emit specific wavelengths of light as they return to their ground state. This results in a unique emission spectrum characteristic of the gas being studied.

The total collection of photons emitted by a given atom is known as its emission spectrum. This spectrum consists of photons with specific energies corresponding to transitions between different energy levels of the atom. The emission spectrum is unique to each element and can be used to identify elements based on the pattern of emitted photons.

Most stars exhibit a continuous spectrum, which contains all wavelengths of light in a continuous distribution. This is often referred to as a blackbody spectrum due to its smooth curve.
