It is [Ar] 3d10 4s2 4p4
[Ar]4s^2 3d^6
The electron configuration of gallium is: [Ar]3d104s24p1.
A half filled sub-shell is more stable than other partially filled shells. As an example use Chromium. It should by logic have the following: Sc = [Ar]4s23d1 Ti = [Ar]4s23d2 V = [Ar]4s23d3 Cr should in theory be Cr = [Ar]4s23d4 but it is not. Half filled shells are more stable so the configuration is Cr = [Ar]4s13d5 two half filled sub levels and then Manganese is Mn = [Ar]4s23d5 one full and one half filled level.
The electron configuration for a ground-state potassium atom is 1s22s22p63s23p64s1. The noble gas shorthand configuration is [Ar]4s1.
[Ar],4s2,3d9
The electron configuration of calcium is [Ar]4s2.
Ground state electron configuration of zinc (Zn): [Ar]3d104s2.
[Ar] 4s2 3d7
Ti3+ has an electronic configuration of the element potassium or [Ar] 4s1
The ground-state electron configuration for a neutral atom of manganese is: 1s22s22p63s23p63d54s2 or [Ar]3d54s2
It is [Ar] 3d10 4s2 4p4
[Ar]4s^2 3d^6
The electron configuration of gallium is: [Ar]3d104s24p1.
The atomic number of zinc is 30. Its abbreviated electron configuration is [Ar]4s23d10 The full electron configuration is 1s22s22p63s23p64s23d10 (configurations for the atom in its ground state. Ions and excited atoms have different configurations).
Br = 1s22s22p63s23p64s23d104p5 or shortened to [Ar] 4s23d104p5 and there are 35 electrons total.
Titanium --------------------------> Ti4+ + 4e-[1s2, 2s22p6, 3s23p6] 3d2, 4s2 --->[1s2, 2s22p6, 3s23p6] + 4 electrons (from 3d and 4s orbital)Ti4+ is iso-electronic to Argon [1s2, 2s22p6, 3s23p6 ], the foregoing noble gas.
