Which of the following elements were not
discovered by the spectroscopic analysis of
their minerals
1) Rb 2) Ga
3) Sc 4) He
Answers
Explanation:
Spectroscopy is the study of the interaction of light with matter. Therefore, it has been used to distinguish between different matters, as each interacts differently with light, in some of the other regions of the electromagnetic spectrum. Thus various elements like Rb,Cs,Tl,In,Ga and Sc were discovered when their minerals were analysed by spectroscopic methods. As each element has specific transition energies which give distinguished absorption/emission spectra. And this specificity can be used as the tool in chemical analysis to identify unknown elements.
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
