Q: What is the electronic configuration of oxygen?
Solution:
Oxygen has 8 electrons, and its electronic configuration is 1s2 2s2 2p4.
Steps: 6
Show Steps
Step 1: Understand that oxygen is an element with the atomic number 8, which means it has 8 electrons.
Step 2: Electrons are arranged in energy levels or shells around the nucleus of the atom.
Step 3: The first energy level can hold a maximum of 2 electrons. So, we fill this level first: 1s2 (2 electrons in the 1s orbital).
Step 4: The second energy level can hold a maximum of 8 electrons. We fill this level next: 2s2 (2 electrons in the 2s orbital).
Step 5: After filling the 2s orbital, we have 4 electrons left to place in the 2p orbital. We fill the 2p orbital with 4 electrons: 2p4.
Step 6: Combine all the filled orbitals to write the complete electronic configuration: 1s2 2s2 2p4.
