Question

match each technological advancement to the experiment it was used for. experiment gold foil experiment determination of electron energy levels cathode ray tube experiment technological advancement isolation of radioactive radium invention of the cathode ray tube understanding of spectroscopy

Explanation:

• Gold foil experiment: Used radioactivity (isolation of radioactive radium helped in studying atomic structure via alpha particles from radium).
• Determination of electron energy levels: Spectroscopy (emission/absorption spectra studied via spectroscopy to find energy levels).
• Cathode ray tube experiment: Invention of cathode ray tube (the experiment itself uses the cathode ray tube).

Answer:

• Gold foil experiment: Isolation of radioactive radium
• Determination of electron energy levels: Understanding of spectroscopy
• Cathode ray tube experiment: Invention of the cathode ray tube
