Q. Which metals can a flame photometer detect?

Answer

In inorganic chemistry, the concentration of ions like sodium, potassium, lithium, and calcium may be determined with the help of a device called a photoelectric flame photometer. Only elements that can be easily ignited at low temperatures will work well in flame photometry. The most common atoms determined with this method are sodium, potassium, lithium, and calcium. The outermost shells of the atoms of elements in the alkali and alkaline earth metals eras are completely filled with just two electrons. The photometer's photodiode analyzes a single wavelength to calculate concentration, therefore adding more leaps dilutes the intensity of that wavelength.
