A selenide contain the anion Se(2-).
The formula for the Selenide ion is Se2-
SrSe
Sr2+ Se2-
The charge of ion selenide is 2-.
Hydrogen Selenide and it is extremely toxic when inhaled.
The chemical symbol of indium is In.
The oxidation states of selenium are: -2, +2, +4, +6.
Ca+2 Se-2 -----> these are the ions and their chargesCalcium selenide (CaSe)-------> the charges must equal zero; since they already do, there is one ion of each in the compound.
When selenium gains two electrons, it becomes the selenide ion.
Krypton and selenide ion are isoelectronic with 36 electrons each
The charge of ion selenide is 2-.
Se-2 ion or selenide ion is the most common.
The most common Selenium ion is Se2- the selenide ion. It is in the same group as oxygen and its most common ion in the oxide ion O2-.
Calcium selenide, CaSe, is formed.
Hydrogen Selenide and it is extremely toxic when inhaled.
The chemical symbol of indium is In.
Krypton and Selenide ion have 36 electrons and are isoelectronic
The oxidation states of selenium are: -2, +2, +4, +6.
the symbol for Oxygen is O, the Oxygen ion is 2-. therefore the symbol for the oxygen ion is O2-
the symbol of ion is base on the lemement that you are trying to fin out
