an atomic emission spectrum can be used to identify an element based on the color, as well as the widths and positions of the spectral lines. black - and - white reproductions of the atomic emission spectra of five known elements and one unknown are shown below. what is the identity of the unknown?

an atomic emission spectrum can be used to identify an element based on the color, as well as the widths and positions of the spectral lines. black - and - white reproductions of the atomic emission spectra of five known elements and one unknown are shown below. what is the identity of the unknown?

Answer

Explanation:

Step1: Compare spectral - line patterns

Compare the width, position and number of spectral lines of the unknown with those of the known elements.

Step2: Identify the match

Find the known - element whose spectral - line pattern most closely matches that of the unknown.

Answer:

Based on the comparison of the spectral - line patterns, the identity of the unknown needs to be determined by visually inspecting which of the known - element spectra (Hydrogen, Helium, Sodium, Copper, Strontium) has the most similar line positions and widths to the unknown. Without the actual visual match details from the image, a specific answer cannot be given. But the process is to match the spectral - line characteristics.
