Atomic emission spectra show specific wavelengths of light emitted by atoms when electrons transition from higher energy levels to lower ones. These spectra typically lie in the visible and ultraviolet regions of the electromagnetic spectrum.

Is an atomic emission spectrum a continuous range of colors?

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.


Who discovered the atomic emission spectra?

The atomic emission spectra were discovered by Gustav Kirchhoff and Robert Bunsen in the mid-19th century. They observed that elements emit light at specific wavelengths when heated, leading to the development of spectroscopy.


What is the significance of the helium lamp spectrum in the study of atomic emission spectroscopy?

The helium lamp spectrum is important in atomic emission spectroscopy because it provides a reference for identifying and calibrating the wavelengths of light emitted by other elements. By comparing the emission lines of unknown samples to the known lines of helium, scientists can determine the elemental composition of a sample.


What is platinum's emission spectra?

Its the light given off when you roast (of fry or even casserole) any element. Like in a light bulb glowing, not all the wavelengths of light are given off equally. By looking at what frequencies are there and which are missing you can tell which element you are looking at. You can tell what a distant star is made of using the same principle.


A maser is a principle of?

A maser is a device that amplifies and emits electromagnetic radiation in the microwave region of the spectrum. It works on the principle of stimulated emission of radiation, similar to a laser but operating at longer wavelengths. Masers are used in scientific research, communication systems, and atomic clocks.

Why do we say atomic spectra are like fingerprints of the elements?

Atomic spectra are like fingerprints of elements because each element has a unique set of discreet emission or absorption lines in its spectrum. These lines correspond to specific energy levels of electrons within the atoms of that element. By analyzing the pattern and position of these lines in a spectrum, scientists can identify the elements present in a sample.

Explain the difference between the continuous spectrum of white light and the atomic emission spectrum of an element?

The difference between continuous spectrum and the atomic emission espectrum of an element is that in emission spectrum, only certain specific frequencies of light are emitted while in a continuous spectrum, a continuous range of colors are seen in the visible light.


How can emission spectra used to identify presence of specific elements in a substance?

In atomic spectroscopy, each element has a unique spectrum. The atomic spectrum obtained from a sample is a combination of the spectra of each elemental component. We take the strongest line from the sample spectrum and determine which elements could have caused it (we call these "candidates"). We then look at the full spectrum from each candidate and see whether or not every major line is present in the sample spectrum. If so, we say that element is present.Then we subtract the spectrum (or spectra) of the element(s) we have determined to be present from the sample spectrum and repeat the same process with the next strongest line in the (leftover) sample spectrum. We continue repeating this process until all lines in the sample spectrum are accounted for.


What are Frequencies of light emitted by an element called?

"Spectrogram" is a word used to describe the set of specific characteristic frequencies of light which are emitted by a given chemical element when it is sufficiently excited by heat or by some other means.Alternatively, a scientific technique known as "spectroscopy" can be used to identify the elements in some matter of unknown composition and also the emission spectra of molecules can be used in chemical analysis of substances.Because each element's emission spectrum is unique, the "emission spectrum" of a chemical element or chemical compound can be used to help identify what it is. The "emission spectrum" is the name given to the relative intensity of each frequency of electromagnetic radiation http://www.answers.com/topic/emission-spectrum by the element's atoms or a compound's molecules when they are returned to a ground state.


Working principle of atomic emission spectroscopy?

Atomic emission spectroscopy works by exciting atoms in a sample to higher energy levels using a flame or electrical discharge. When the atoms return to their ground state, they emit characteristic wavelengths of light. By analyzing the emitted light, the elemental composition of the sample can be determined.


What element can produce an atomic emission spectrum in its natural state neon chlorine silicon or Krypton?

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.


The lines in the bright line spectrum of an atom are due to what?

The atomic line spectrum comes from the emission of atoms of different elements that are in an excited state. Each element has its own unique atomic emission spectrum.
