1s2 2s2 2p6 3s2 3p4
The symbol for sulfur is S. Its electron configuration is 1s22s22p63s23p4
Minor quibbling about the format of the question aside, sulfur is the element with that ground state electronic configuration.
The electron configuration of sulfur in the excited state is [Ne] 3s2 3p4, rather than the ground state configuration of [Ne] 3s2 3p4. In the excited state, an electron has moved from the 3p orbital to a higher energy level.
The element with that electron configuration is Iron.
The electron configuration of a sulfur atom in its ground state is 1s2 2s2 2p6 3s2 3p4. In an excited state, one of the electrons can be promoted to a higher energy level. For example, in an excited state, the electron configuration of a sulfur atom could be 1s2 2s2 2p6 3s1 3p5.
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.
The electron configuration of sodium in its ground state is 1s2 2s2 2p6 3s1. This is not an excited state configuration, as the electrons are in their lowest energy levels available in the atom. Excited states occur when electrons are in higher energy levels than the ground state configuration.
The ground state electron configuration for nitrogen is [He]2s2.2p3.
The ground state electron configuration of bromine is Ar 4s 3d 4p.
The ground-state electron configuration for the V3 ion is Ar 3d2.
Ground state electron configuration of zinc (Zn): [Ar]3d104s2.
The ground state electron configuration for iron (Fe) is Ar 3d6 4s2.
