1s 2 2s 2 2p 1
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.
1s22s22p1
The oxidation state of boron is either three electrons or one electron. Boron has an valence electron configuration of ns2np1.
Ground state electron configuration of zinc (Zn): [Ar]3d104s2.
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.

The ground state electron configuration for nitrogen is [He]2s2.2p3.
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.
The ground state electron configuration of the hydrogen atom is 1s1, and for helium it is 1s2.
ground state
The symbol for sulfur is S. Its electron configuration is 1s22s22p63s23p4
The most likely electron configuration for a sodium ion in its ground state is 1s22s22p63s1.
The ground-state electron configuration for a neutral atom of manganese is: 1s22s22p63s23p63d54s2 or [Ar]3d54s2
It depends on the atom. For example, the electron configuration of an atom of boron in the ground state is 2-3. In the excited state, it would be 2-2-1. For an atom of chlorine, the ground state configuration is 2-8-7. The excited state would be 2-8-6-1. When an atom enters the excited state, an electron moves up to a higher energy level and releases energy. An electron in the excited state is not stable until it returns to ground state.
