It is [Ar] 3d10 4s2 4p4
The electron configuration for a ground-state potassium atom is 1s22s22p63s23p64s1. The noble gas shorthand configuration is [Ar]4s1.

The aufbau principle is a method for determining the electron configuration of an element. It shows how the various orbitals must be filled in correct sequence to show how ionization may occur. For selenium, the correct aufbau sequence is [AR] 4s2 3d10 4p4.
The ground state electron configuration for nitrogen is [He]2s2.2p3.
The ground state electron configuration of the hydrogen atom is 1s1, and for helium it is 1s2.

The aufbau principle is a method for determining the electron configuration of an element. It shows how the various orbitals must be filled in correct sequence to show how ionization may occur. For selenium, the correct aufbau sequence is [AR] 4s2 3d10 4p4.
The electron configuration of 1s22s22p3s1 is not the ground state electron configuration of any element. This configuration contains 8 electrons, which in the ground state would be oxygen. The ground state configuration of oxygen is 1s22s22p4.
I believe ground state menas in its noble gas form therefor all elements in period 2 such as nitrogen have a ground state of He
Ground state electron configuration of zinc (Zn): [Ar]3d104s2.
ground state
The ground state electron configuration for nitrogen is [He]2s2.2p3.
The ground state electron configuration of the hydrogen atom is 1s1, and for helium it is 1s2.
The ground state electron configuration for sodium is 1s2 2s2 2p6 3s1
The expected ground-state electron configuration of copper is ; however, the actual configuration is because a full dsubshell is particularly stable. There are 18 other anomalous elements for which the actual electron configuration is not what would be expected.
