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 is selenium a non metal?
Selenium has no metallic propeties, it isn't shiny, an electrical conductor etc. It forms anions, Se2-.
Who made Selenium?
Jons Jacob was the man to discover Selenium.
Is selenium a nonmetal?
Yes. selenium is a non metal
Is selenium a mixture?
No, selenium is a element

How laser printer works?
A laser printer uses lasers into order to receive information through a photoreceptor. A drum inside the printer is coated with selenium to pick up toner that is then used to make the image on the paper.
Which element is likely to be the most brittle out of selenium cobalt platinum or zinc?
Selenium is the most brittle of the elements listed: The others are all full metals, but selenium is only a semi-metal or a metalloid, and ductility, the negative of brittleness, is a property primarily of metals.
Are there any metals in an older Xerox copier to salvage?
Older Xerox machines designed as copiers and printers will contain:copper wiringsteel and aluminum partsarsenic/selenium alloy
Which member of the oxygen family is a metal?
Selenium, tellurium, and polonium are metalliod semiconductors (that means, their electrical properties are between those of a metal and an insulator). Nevertheless, tellurium, as well as selenium, is often referred to as a metal when in elemental form.

What is the correct name for SeF6?
This compound is called selenium hexafluoride.
What element is represented by the symbol Se?
Selenium, atomic number 34.
How is static electric used in photocopiers?
A selenium coated drum is rubbed onto a brush. The selenium coated drum is positively charged.The light is shined onto the page that is to be copied. Being reflected through several mirrors, it is finally reflected onto the selenium coated drum.The selenium becomes conductive as the light hits it. The charges get rearranged until the charge is neutral. There is only positive charge on the parts of the drum where there was no light- the silhouette of the print on the page being photocopied.There is a brush that picks up negatively charged toner (a fine black powder) made of plastic beads and carbon particles. When the brush rolls onto the selenium, the negative toner is attracted to the positive charge left on the drum.Positively charged paper picks up the toner from underneath the selenium coated drum.The paper is finally heated to melt and seal the toner onto the paper.
Is selenium a nonmetal?
Yes. selenium is a non metal
