Atomic emission spectrum of copper
Ten tons of
copper was ordered by a bridge building company. The copper was used to
construct giant load bearing supports. It soon became obvious that the
copper was severely weakend and contaminated with an impurity. An industrial
chemist was asked to investigate. Emission spectra of the copper were
developed and revealed some interesting results.
Hydrogen
On the left are the emission spectra of some well known elements. Identify the impurity present that has caused the copper to become weak.
Helium
Sulfur
