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-.
Se-2 ion or selenide ion is the most common.
The electron configuration of selenium for a 2- ion is [Kr]4s2.3d10.4p6.
I^- is the most common ion of Iodine.
When selenium gains two electrons, it becomes the selenide ion.
Se-80 is the most common isotope.
Se-2 ion or selenide ion is the most common.
The oxidation states of selenium are: -2, +2, +4, +6.
The ion Se4+ is common.
Selenium is not a common element but is necessary.
The electron configuration of selenium for a 2- ion is [Kr]4s2.3d10.4p6.
I^- is the most common ion of Iodine.
This chemical element is selenium.
When selenium gains two electrons, it becomes the selenide ion.
Se-80 is the most common isotope.
P3- is the most common ion of phosphor. Howver, when combined with other elements such as oxygen, the phosphate ion PO43- is the most common.
selenium
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.
