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.
What kind of metals is atomic emission spectrometry especially sensitive for?
It is especially sensitive for alkali metals.
What are the applications of atomic emission spectrometry in pharmaceutics?
Atomic emission spectrometry is used to quantify alkali metals in alkali metal salts, infusion, and dialysis solutions. It is used used to determine the presence of metallic impurities in some of the other inorganic salts used in preparing these solutions.
What is the use of atomic absorption spectrometry in food industries?
Atomic absorption spectrometry is used in food industries to accurately determine the concentration of trace elements like heavy metals (e.g. lead, mercury) and essential nutrients (e.g. iron, zinc) in food samples. This helps in ensuring food safety by monitoring contamination levels and assessing nutritional quality.
Name Four methods of identifying metal?
Methods of analytical chemistry: - for some metals the flame test is possible - qualitative analysis with specific reagents - emission spectrography - X-ray spectrometry - ICP mass spectrometry and many other

What are the Advantages and disadvantages of atomic emission spectrometry?
Atomic emission spectrometry (AES) offers several advantages, including its ability to detect multiple elements simultaneously, high sensitivity, and rapid analysis times. It is particularly effective for trace analysis in various samples, such as metals and alloys. However, disadvantages include potential interferences from overlapping spectral lines and the requirement for careful calibration. Additionally, AES may not be suitable for all types of samples, particularly complex organic matrices.

Are alkali metals suitable for photo electric emission?
yes alkali metals are suitable for photo electric emission
Is it possible for two metals to have the same emission spectrum?
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.

How do different metals affect emission of electrons?
Different metals have different work functions, which determine the amount of energy required to remove an electron from the surface of the metal. Metals with lower work functions typically exhibit higher electron emission because it requires less energy to release an electron. Additionally, the surface properties of the metal can affect electron emission, such as roughness or cleanliness, which can impact the efficiency of the emission process.
What is the difference between the emission colours produced by the alkali metals and calcium?
Fish
What happens to the chemical reactivity of alkali metals as you increase atomic numbers?
The chemical reactivity of alkali metals increase when the atomic number increase.
What is the emission of electrons from a metals surface when light of a certain frequency shines on it?
photoelectric effect
