In Aufbau Principle, the electrons are filled according to the increasing energy level of orbitals. However there are numerous exceptions; for example the lightest exception is chromium, which would be predicted to have the configuration 1s 2 2s 2 2p 6 3s 2 3p 6 3d 4 4s 2, written as [Ar] 3d 4 4s 2, but whose actual configuration given in the table below is [Ar] 3d 5 4s 1. Note that these electron configurations are given for neutral atoms in 18: 1: 30 Zn zinc: [Ar] 3d 10 4s 2; 1s 2: 2s 2: 2p 6: 3s 2: 3p 6: 3d 10: 4s 2: 2: 8: 18: 2: 31 Ga gallium: [Ar] 3d 10 4s 2 4p 1; 1s 2: 2s 2: 2p 6: 3s 2: 3p 6: 3d 10: 4s 2: 4p 1: 2: 8: 18: 3: 32 Ge germanium: [Ar] 3d 10 4s 2 4p 2; 1s 2: 2s 2: 2p 6: 3s 2: 3p 6: 3d 10: 4s 2: 4p 2: 2: 8: 18: 4: 33 As arsenic: [Ar] 3d 10 4s 2 4p 3; 1s 2: 2s 2: 2p 6: 3s 2: 3p 6: 3d 10: 4s 2: 4p 3: 2: 8: 18: 5: 34 Se selenium: [Ar] 3d 10 4s 2 4p 4; 1s 2: 2s 2: 2p 6: 3s 2: 3p 6: 3d 10: 4s 2: 4p 4: 2: 8: 18: 6: 35 Br The M shell contains 3s, 3p, and 3d, and can carry 18 electrons. The N shell containing 4s, 4d, 4p and 4f, can carry 32 electrons. Such an arrangement helps explain the periodicity and periodic trends observed across the elements of the periodic table. Subshell Configurations Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), Radon (Rn) in the periodic table belong to group-18, or zero-group with the general electronic configuration of the valence electron of noble gases ns 2 np 6, where n = 1 to 6.

The ground state electron configuration for arsenic is: (a) [Ar] 4s2 4p13 (b) [Kr] 4s2 4p1 (c) 1s2 2s2 2p6 3s2 3p6 3d12 4s2 4p1 (d) 1s2 2s2 2p6 3s2 3p6 4s2 3d8 4p5 (e) 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p3 7. The outer electronic configuration 3s23p4 corresponds to which one of the following elements in its ground state?

Such an arrangement helps explain the periodicity and periodic trends observed across the elements of the periodic table. Subshell Configurations Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), Radon (Rn) in the periodic table belong to group-18, or zero-group with the general electronic configuration of the valence electron of noble gases ns 2 np 6, where n = 1 to 6.

The first notation follows the order based on the Madelung rule for the configurations of neutral atoms; 4s is filled before 3d in the sequence Ar, K, Ca, Sc, Ti. The electron configuration for Ar is 1s2 2s2 2p6 3s2 3p6. 18. The ground state electron configuration of As is _____. Which of the following is the ground state electron configuration of Zn 2⁺?
