How do you find the charge of selenium?
The oxydation states of selenium are: -2, +2, +6, +4.
What is the normal ionic charge for selenium?
-2
What is the charge on the ion that selenium form ionic compound?
selenium has a -2 charge. when it forms a compound with another atom the charge of the compound should be zero unless it has a cahrge in its equation. when compounds form they try to be in the most stable state which is when all their valance elctrons are full which means the charge is zero.
Is selenium fluoride polar?
Selenium fluoride bond is polar because fluorine is more electro-negative than selenium. Hence the shared paired of electrons are more towards fluorine giving fluorine a partial negative charge and selenium a partial positive charge.
How many electrons does the element selenium have with the charge of negative 2?
It should gain 2 electrons
Does selenium have a positive or negative charge?
Selenium form anions.

What is the ionic charge for selenium?
Selenium, when forming an ion, gains two electrons. The name of the anion is Selenide, and it has a -2 charge. I found this by looking at the periodic table. Find Selenium, number 34, and you can see that two spaces to its right is a noble gas. This means is gains two electrons when forming an ion. I hope I helped.
How many ion atom are formed in selenium?
The oxidation states of selenium are: -2, +2, +4, +6.
How many electrons are in a selenium ion?
Selenium has 34 total electrons. It has 6 valence electrons.
How many electrons are gained or lost when selenium forms an ion?
Since Selenium is a Chalcogen (meaning it's in group 6A on the Periodic Table), it gains 2 electrons to form an ion with a charge of -2.
Who made Selenium?
Jons Jacob was the man to discover Selenium.
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.
