What is the name for a selenium ion with 36 electrons?
When selenium gains two electrons, it becomes the selenide ion.
How many electrons will selenium lose or gain in forming an ion?
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
How many electrons does selenium gain or lose in forming an ion?
Selenium can gain 1 electron or loss 2, 4, 6 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.
Will selenium form a 2- ion?
Yes it will. Selenium has 6 valence electrons. If it accepts two more electrons to form Se2-, the resulting ion will have octet of electrons in the valence shell and will be stable.
How many valence electrons in selenium?
6 valence electrons
What ion will be formed by a selenium atom when it has a stable set of valence electrons?
Se2-Se 2-
