How atomic absorption and atomic emission are similar?
Atomic absorption and atomic emission are both analytical techniques used to identify and quantify elements in a sample based on their atomic properties. Both methods rely on the characteristic absorption or emission of light at specific wavelengths by the sample's atoms when they undergo electronic transitions. Additionally, they can both provide information about the concentration and presence of different elements in a sample.
What is the difference between AAS and Flame photometer?
flame photometry is a type of atomic EMISSION spectroscopy. The sample is excited (raised to a high temperature), causing the emission of light. the wavelength of the emitted light is a function of the energy of the excited electrons, so each element has a characteristic set of wavelengths. usually a single wavelength is detected and the intensity of the emission is used to calculate concentration. Atomic adsorption works in the reverse way. A light of a standard wavelength (a wavelength characteristic of the target element) is passed through a flame containing the unknown substance, and the concentration of the target element is determined by the reduction in the energy of this light as it passes through the flame. the light is adsorbed by the electrons in the target element, kicking them into a higher orbit or completely out of the atom, depending on the energy involved. basically, one method involves the emission of the energy as an excited electron kicks back down to a lower state, and the other involves the adsorption of energy as an electron is kicked up an energy state. Same basic principle-change in electron energy relates to light of a specified wavelength and the change in the amount of that light can be measured and converted to a concentration.
If an isotope undergoes beta emission?
If an isotope undergoes beta emission, a neutron in the nucleus is transformed into a proton, along with the emission of a beta particle (an electron) and an antineutrino. This process increases the atomic number of the nucleus by one but leaves the mass number unchanged.
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 does radon-222 decay by alpha emission?
Radon-222 decays by alpha emission through the release of a helium nucleus, which consists of two protons and two neutrons. This process reduces the atomic number of the radon atom by 2 and the atomic mass by 4.
Does atomic emission come from the sun?
there is no atomic emission from the sun.
Advantages and disadvantages of atomic emission spectrometry?
advantages of atomic emission
What are the strenghts of atomic absorption spectrometry compared to atomic emission spectrometry?
Atomic absorption spectrometry is more sensitive than atomic emission spectrometry.
What kind of metals can be quantified by atomic emission spectrometry?
Atomic emission spectrometry is limited to alkali metals.
When is atomic absorption more sensitive than atomic emission in atomic absorption spectrometers?
Atomic absorption is more sensitive to atomic emission when the excitation potential is greater than 3.5eV.
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.
Is spectral interference more common in atomic emission spectroscopy or atomic absorption spectroscopy?
Spectral interference is more common in atomic emission spectroscopy due to overlapping spectral lines.
What light rays have the longest wavelength?
The longest wavelength photon I could find out about was in a maser (microwave version of a laser) which uses emission between two hyperfine levels of atomic hydrogen. This had a frequency of 1.4 GHz and a wavelength of 21cm.
What are the strenghts of limitations of atomic emission spectrometry?
Atomic emission spectrometry is a selective method for quantifying some types of metals. It is also cheap and robust. However, atomic emission spectrometry is only applicable to the determination of alkali metals and some alkaline earth metals.
