Science Students Discover Elements Have Finger Prints, Too!


 

ELEMENTS HAVE FINGER PRINTS, TOO!

In the photo, a DuBois Central Catholic junior uses a spectroscope to split light into its component wavelengths while a fellow junior and lab partner heats one of six metal salts using the Bunsen burner.    According to Chemistry instructor Lisa Bradley, the lab measured the electron configuration of six different metallic elements.  When the metals are heated, the electrons get energized and jump up to higher energy level, then give off light energy. Students experimented with identifying metals by the spectrum of light they produced, which is specific to each element, and can be compared to humans being identified by their fingerprints.
