When a metal is heated in a flame, the electrons absorb energy and jump to higher energy state. On coming back to the lower energy state, they emit light, which we can observe in -

A. Raman spectra
B. Absorption spectra
C. Emission spectra
D. Fluorescence
Answer» C. Emission spectra
Explanation: When a metal atom is strongly heated, its electrons absorb the heat energy and jump to a higher energy level. When the electron returns to its original position it gives off-the energy it absorbed in the form of light. The result of all these jumps is to produce what is called an emission spectrum. An emission spectrum is a set of coloured lines that correspond to the energy the electron has released at each stage °fits fall back to its original state.
