Why do photographers work with low light with selenium?
Materials with Selenium are very sensitive to light. If a photographer is working with a lot of light, the materials will be destroyed and they will not be able to take any pictures.
Why is the metal plate coated with selenium in a photocopier?
First a special selenium coated, flat metal plate is positively charged. Light stones through a lens then projects an image of the page to be copied onto the charged plate. Whenever the light falls on the selenium plate the plate becomes a conductor and the positive charge is conducted away from the selenium by the metal plate.
Why selenium is photo conductor?
when light falls on the it its electrons become excited and become free for conductivity that's why selenium is a photo conductor
What conducts electricity when exposed to light so it is used in solar cells and in light meters?
Selenium
Is selenium a metal or a non metal?
Nonmetal because Selenium is used to make light sensors so it cant melt at low temperatures and it conducts electricity at a low level like a lot of non - metalsSelenium is considered a nonmetal.

Does selenium have any colour?
Different allotropes of Selenium have different colors. They can be Black, Grey, Red or Purplish.
The black form of this non metal conducts electricity better when light is shined upon it?
The Answer is Selenium. Symbol of the element is SE.

The black form of this nonmetal conducts electricity better when light is shined upon it and it is used in Xerox toner?
Selenium is the nonmetal that conducts electricity in its black form when light shines on it. But selenium is not a component of Xerox toner. Selenium is used in the older photoreceptor drums and belts that serve as the equivalent of film in a camera.

Nonmetal because Selenium is used to make light sensors so it cant melt at low temperatures and it conducts electricity at a low level like a lot of non - metalsSelenium is considered a nonmetal.
Conducts electricity when exposed to lightnso it is used in solar cells and in light meters?
Selenium
This element's resistance to the flow of electricity is greatly affected by the amount of light shining on it?
Selenium
