The spectra of different elements can be distinguished because
A)they have the same spectral lines,but the lines are of different intensities.
B)they have spectral lines in different positions.
C)every element has one unique spectral line.
D)none of the above

Question

Quizplus · Accepted Answer

Each element has a unique arrangement of electrons, and when these electrons are excited, they emit energy in the form of light in specific wavelengths. These wavelengths manifest themselves as distinct spectral lines that are unique to each element. Therefore, the spectra of different elements can be distinguished because they have spectral lines in different positions.
