Photoelectrons
Electrons emitted from the surface of a metal by the photoelectric effect.
3 of 7
Electronvolt
A derived unit of energy used for subatomic particles and photons, defined as the energy transferred to or from an electron when it passes through a potential difference of 1V.

Gold-Leaf Electroscope
A device with a metallic stem and a gold leaf that can be used to identify and measure electric charge - a device that was historically used as a voltmeter for measuring large voltages.
