The electronic configuration of tin is: [Kr]D10.5s2.5p2.
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.
The electronic configuration of copper is Ar 3d10 4s1.
The electronic configuration of Bromine is [Ar] 3d10 4s2 4p5.
Selenium: [Ar] 3d10 4s2 4p4 or 2, 8, 18, 6 Phosphorus: [Ar] 3d10 4s2 4p3 or 2, 8, 18, 5
Selenium typically loses 2 electrons to achieve a stable electron configuration. This results in the formation of a 2+ ion for selenium.
