Answer
Brief Explanations:
Oxygen has an atomic number of 8, meaning it has 8 electrons. Electrons fill orbitals in the order 1s, 2s, 2p etc. The 1s orbital can hold 2 electrons, the 2s orbital can hold 2 electrons, and the 2p orbital can hold 6 electrons. For 8 electrons, the configuration is 1s²2s²2p⁴.
Answer:
1s²2s²2p⁴
