which is the electronic configuration for oxygen? 1s²2s²2p¹ 1s²2s²2p³ 1s²2s²2p⁴ 1s²2s²2p⁶
Answer
Explanation:
Step1: Recall oxygen's atomic number
Oxygen has an atomic number of 8, meaning it has 8 electrons.
Step2: Fill electron - shells and sub - shells
We fill electrons according to the Aufbau principle. The 1s sub - shell can hold 2 electrons, the 2s sub - shell can hold 2 electrons, and the remaining 4 electrons go into the 2p sub - shell. So the electron configuration is $1s^{2}2s^{2}2p^{4}$.
Answer:
$1s^{2}2s^{2}2p^{4}$
