Detail about MCQs

The element whose salts do not impart color to a flame test is:
C. Ca (Calcium)
Calcium salts typically do not produce a characteristic color in a flame test. In flame tests, certain metal ions emit distinct colors when heated in a flame due to the excitation of electrons to higher energy levels and their subsequent relaxation. While elements like potassium (K) can produce a violet flame, calcium (Ca) usually does not impart a noticeable color to the flame test.
