The electronic configuration of tin is: [Kr]D10.5s2.5p2.
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.
Bromine (Br) has atomic number 35, so it contains 35 electrons. Electronic configuration: 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁵ Shell-wise configuration: 2, 8, 18, 7 Valence electrons: 7 Period: 4 Group: 17 (halogens)
The electronic configuration of copper is Ar 3d10 4s1.
