Document Content and Description Below
1 The element magnesium is an important Group 2 metal. Its presence in distant stars has been shown using atomic emission spectra. (a) (i) The atomic emission spectrum of an element shows a series o... f coloured lines on a black background. Describe how the appearance of the absorption spectrum of the element is similar to and different from its emission spectrum.
