A selenide contain the anion Se(2-).
The net charge of selenide is -2. Selenide is an anion that carries a charge of -2 due to the gain of two electrons in order to achieve a stable electron configuration.
The formula for cobalt(II) selenide is CoSe. It is composed of one cobalt ion (Co^2+) and one selenide ion (Se^2-).
The chemical symbol of indium is In.
The ion bromide is Br-.
The symbol for the fluoride ion is F-.
When selenium gains two electrons, it becomes the selenide ion.
Krypton and selenide ion are isoelectronic with 36 electrons each
