Answer
Answer:
1s² 2s² 2p⁴
Explanation:
Step1: Recall oxygen's atomic number
Oxygen has atomic number 8.
Step2: Fill electrons according to rules
Electrons fill orbitals in order. 1s can hold 2 electrons, 2s can hold 2 electrons, and then 2p starts filling. After filling 1s² and 2s², we need to place 4 more electrons in 2p, resulting in 1s² 2s² 2p⁴.
