Write the full ground state electron configuration of o2 .

Electron configuration is the dissemination of electrons of an atom or molecule in molecular orbitals. Oxygen is composed of eight electrons in its atom, wherein there are two in 1s subshell; then two in 2s subshell; then four in 2p subshell. Its full ground electron configuration is: 1s^2 2s^2 2p^4
