Transition metals cannot be accurately determined by flame photometry because they typically have multiple oxidation states, leading to complex emission spectra that are difficult to interpret. Additionally, transition metals often form stable complexes with other compounds in the flame, further complicating the analysis. As a result, flame photometry is not suitable for the precise determination of transition metals, and other analytical techniques such as atomic absorption spectroscopy or inductively coupled plasma spectroscopy are more commonly used for their quantification.
flame photometry involves the determination of concentration of alkali and alkaline earth metals present in a sample based on the radiation emitted by it when the sample is atomized to a flame
The color of the salt solution or solid can indicate the presence of a transition metal ion, as transition metal ions often exhibit colorful compounds. Additionally, conducting flame tests can help identify the presence of specific transition metal ions based on the color of the flame produced. Spectroscopic techniques can also be used to identify transition metal ions based on their characteristic absorption or emission patterns.
The subscript of the second ion identifies the oxidation state of the transition metal
Sea water is diluted before flame photometry to reduce the salt content, which can interfere with the measurement of specific elements. The high salt concentration in sea water can lead to high background noise and inaccurate readings, so dilution is necessary to obtain accurate results for trace metal analysis.
How to determine these ions:metal cations: find the positive charge, and make sure it is qual to the group numbernonmetal anions: subtract 8 from the group numbertransition metals cations: the number of electrons lost
Examples: emission spectrometry, flame photometry, atomic absorption, etc.

A pure metal has the oxidation state zero.
Yes, transition metals can be identified by their unique colors in flame tests. Each transition metal emits a characteristic color when exposed to a flame due to the energy levels of their electrons transitioning. This property is used in qualitative analysis to identify the presence of specific transition metals in a sample.
