Why does selenium not have a second electron affinity?

Selenium does not have a second electron affinity because adding an additional electron to selenium would require more energy to overcome the repulsion between the negatively charged electron and the negatively charged selenium ion. In other words, the energy required to add a second electron to selenium is higher than the energy released in the process.


Which has the lower electron affinity germanium or selenium?

Selenium has a lower electron affinity than germanium. Electron affinity is the energy released when an atom gains an electron to form a negative ion. In general, electron affinity tends to decrease as you move down a group in the periodic table, which is why selenium has a lower electron affinity than germanium.

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).


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 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.
