The electron configuration of selenium (Se) is [Ar] 3d10 4s2 4p4. To form a 2- ion, two electrons will be removed from the outermost shell, which is the 4p subshell. Therefore, the electron configuration of Se2- is [Ar] 3d10 4s2.

How many atoms selenium lose?

Selenium typically loses 2 electrons to achieve a stable electron configuration. This results in the formation of a 2+ ion for selenium.

What ion will be formed by a selenium atom when it has a stable set of valence electrons?

Selenium typically forms an ion with a charge of -2 when it gains two electrons to achieve a stable electron configuration. This forms the selenide ion (Se2-).

What is the electron configuration of selenium and phosphorus?

The electron configuration of selenium is [Ar] 3d10 4s2 4p4. The electron configuration of phosphorus is [Ne] 3s2 3p3.

What are selenium ions?

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.
