Electron Configuration Of Oxygen In Excited State

The ground state electron configuration of an element is the same as the regular configuration in which the electrons are in the lowest possible energy state. The electron configuration of an exited state of oxygen is 1s2 2s2 2p3 3s1 but my question is why it is not 1s2 2s1 2p5 how to determine which electron in which orbital is move to the another? Viewed simply, electrons are arranged in shells around an atom’s nucleus.

Like for a if there were two up arrows in two separate boxes in the 2p orbitals it would be in its ground state.

Electron configuration of oxygen in excited state. This is the metastable state referred to by the term \singlet oxygen; Its rest state wants to have a filled 4s^2 shell. The first excited state is obtained by promoting a 3s electron to the 3p orbital, to obtain the 1s 2 2s 2 2p 6 3p 1 configuration, abbreviated as the 3p level.

Atomic number of oxygen is 8, so it has total 8 electrons. The singlet states of oxygen are 158 and 95 kilojoules per mole higher in energy than the triplet ground state of oxygen. It is filling in the normal order;

Oxygen is the eighth element with a total of 8 electrons. 1s^2 2s^2 2p^4 where the 2p orbitals. The two singlet states are denoted 1 σ + g and 1 δ g (the preceding superscript 1 indicates a singlet state).

If the energy of an atom is increased, an electron in the atom gets excited. Each orbital can hold 2 electrons maximum, and there are 2l+1 of each type of orbital (s,p,d,f,g,.), where l = 0 corresponds to an s orbital, l = 1 means p orbital, and so on. Hence, in excited state one of the 2s electron will jump to 2p orbital,so the excited state electronic configuration should be 1s2 2s1 2px2 2py1 2pz1.

Singlet oxygen refers to one of two singlet electronic excited states. Any other configuration is an excited state. The 4s electrons are at a lower energy level than 3d electrons

How to write the electron configuration for oxygen. The one closest to the nucleus is called the ‘first excited state’ (lowest energy), whereas, the second farther is called the ‘second excited state’, and so on. Is this an excited state of oxygen?
