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-.
Selenium ions refer to selenium atoms that have gained or lost electrons to become positively or negatively charged. They can exhibit different chemical properties compared to neutral selenium atoms, depending on the number of electrons gained or lost.
The most common isotope of selenium is selenium-80, which makes up about 50% of naturally occurring selenium.
When selenium gains two electrons, it becomes the selenide ion.
I^- is the most common ion of Iodine.
Selenium typically forms a negative ion (selenide) by gaining two electrons rather than losing them. However, if it were to lose electrons, it would usually lose six to achieve a stable electron configuration, as it has six valence electrons. In its most common ionic form, selenium gains electrons to complete its outer shell, rather than losing them.
The oxidation states of selenium are: -2, +2, +4, +6.
The ion Se4+ is common.

Selenium is not a common element but is necessary.
When selenium gains two electrons, it becomes the selenide ion.
I^- is the most common ion of Iodine.
Selenium typically has 34 electrons in its neutral state. To determine the number of electrons in a selenium ion, you need to know the specific charge of the ion. For example, a selenium ion with a charge of +2 would have 32 electrons, while a selenium ion with a charge of -2 would have 36 electrons.
The most common fluorine ion is fluoride (F-) ion.
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.
The most common ion for cesium is Cs+ (cesium ion). This ion has a charge of +1.
