Ground state: 1s2 2s2 2p6 3s2 3p6 4s1
Excited state: 1s2 2s2 2p6 3s2 3p6 4p1
The 4s1 electron jumped into the 4p sublevel, which has higher energy than the 4s sublevel. This is very unstable, and the electron will drop back down into the 4s sublevel, emitting radiation, including visible light.
This is not the only possible excited state, but is just one example.

What is the electron configuration of calcium in its excited state?
The electron configuration of calcium is [Ar]4s2.
Is the electron configuration of sodium an excited state or ground state?
ground state
What is the electron configuration of copper at excited state?
[Ar],4s2,3d9
The electron configuration for a Sulfur atom in the excited state?
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.

The electron configuration Ar4s1 is the ground state electron configuration of?
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.
