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 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.

What is the core notation for the electron configuration of a cobalt 2 ion?

The core notation for the electron configuration of a cobalt 2 ion is [Ar] 3d7. The [Ar] represents the electron configuration of the argon noble gas, which has the electron configuration 1s2 2s2 2p6 3s2 3p6. The 3d7 indicates that there are seven electrons in the 3d subshell of the cobalt ion.


Electron configuration of a flouride ion?

The fluoride ion has the same electron configuration as a neon atom. This is because fluoride has gained an extra electron compared to a neutral fluorine atom, resulting in a full valence shell with 8 electrons. Therefore, the electron configuration of a fluoride ion is 1s2 2s2 2p6.


What is A monatomic ion with a charge of -1 has an electronic configuration of 1s22s22p63s23p64s23d104p65s24d105p6?

The monatomic ion with a charge of -1 has gained one electron, so its electron configuration will be the same as the original atom with an additional electron. Therefore, the electron configuration of the ion will be 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^6.
