which is the electronic configuration for oxygen? 1s² 2s² 2p¹ 1s² 2s² 2p³ 1s² 2s² 2p⁴ 1s² 2s² 2p⁶
Answer
Brief Explanations:
Oxygen has an atomic number of 8. The first - shell (1s) can hold 2 electrons, the second - shell's s - subshell (2s) can hold 2 electrons, and the remaining 4 electrons go into the 2p subshell. So the electron configuration is $1s^{2}2s^{2}2p^{4}$.
Answer:
$1s^{2}2s^{2}2p^{4}$ (the option corresponding to this configuration in the multiple - choice list)
