What is the valence electron configuration of selenium?
The valence electron configuration of selenium is 4s2 4p4, meaning it has 6 valence electrons.
What is the electron configuration of selenium 2 ion?
Se2- 1s22s22p63s23p64s23d104p6
What is the electron configuration of selenium for a 2- ion?
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 filled shells in selenium?
Selenium has 5 filled electron shells. The electron configuration for selenium is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p4.
How many electrons must be gained or lost for selenium to achieve a noble gas electron configuration?
Selenium should gain two electrons and lose six electrons to achieve a noble gas electron configuration.
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 bond is formed between potassium and selenium?
Potassium and selenium can form an ionic bond, where potassium will donate an electron to selenium to achieve a stable electron configuration. This results in the formation of potassium selenide (K2Se).
Which electron configuration represents a selenium atom in an excited state?
Excited electrons are on higher levels of the electron clouds. It takes more energy to get them to the higher level, and energy is lost when they fall. When that energy is lost, a an x-ray photon is emitted.
What is the noble gas configuration for selenium?
The noble gas configuration for selenium is [Ar] 3d10 4s2 4p4, which means it has the same electron configuration as argon, followed by 4d10 4p4 electrons.
