when light falls on the it its electrons become excited and become free for conductivity that's why selenium is a photo conductor
Selenium is a non metal, and non metals are poor conductors due to the lack of free electrons or ions.
Selenium is a nonmetal because it lacks the physical and chemical properties of metals. It tends to gain electrons in reactions rather than losing them like metals, and it is brittle in solid form rather than malleable and ductile like metals. Additionally, selenium is a poor conductor of heat and electricity, unlike metals.
A selenium camera is a type of light metering system that uses a selenium cell to measure the amount of light available for a photograph. It is commonly found in older film cameras and works by converting light into an electrical current which helps to determine the optimal exposure settings for a photo.
There is one mole of selenium in one mole of selenium tetrafluoride, as the formula for selenium tetrafluoride is SeF4. Therefore, there is 1 mole of selenium in 1 mole of selenium tetrafluoride.
Yes. selenium is a non metal
Yes, a photo conductor works in every printer.
Selenium has no metallic propeties, it isn't shiny, an electrical conductor etc. It forms anions, Se2-.
Selenium is a non metal, and non metals are poor conductors due to the lack of free electrons or ions.
The element that is a good conductor that begins with the letter S is Selenium. Another choice could be Scandium.

It used to be Selenium, but modern photocells use silicon (Si).
Most laser printer drums are coated with selenium. Selenium is a nonmetallic element with photovoltaic and photo-conductive properties that make it ideal for this use.

Silicon (Si), Selenium (Se), Samarium (Sm), maybe Seaborgium(Sg), Strontium (Sr), Scandium(Sc)...many elements with letter s and is good conductor
Among the options provided, selenium is the best conductor of electricity. It is a semiconductor, meaning it can conduct electricity under certain conditions, unlike arsenic, bromine, phosphorus, and sulfur, which are generally poor conductors. Selenium's electrical conductivity makes it useful in various electronic applications, including photodetectors and solar cells.
This compound is called selenium hexafluoride.
answer 2 A photocell is a device that converts light energy into electrical output.From memory (?) selenium cells were the early photodetectors used on ancient photo equipment. (My Weston photo meter.)It was not too difficult to improve on the selenium photocells.Nowadays we are spoilt for choice for types of photocells, up to sophisticated photomltipliers, and solid state detectors that have completely replaced film for astronomy recording material.
