Q
Q: What is the electron configuration of oxygen (O)?
Solution:
The electron configuration of oxygen (atomic number 8) is 1s2 2s2 2p4.
Steps: 8
Show Steps
Step 1: Identify the atomic number of oxygen, which is 8. This means oxygen has 8 electrons.
Step 2: Electrons fill energy levels starting from the lowest. The first energy level can hold up to 2 electrons.
Step 3: Place 2 electrons in the first energy level (1s), so we write 1s2.
Step 4: Move to the second energy level, which can hold up to 8 electrons. The second level has two sub-levels: 2s and 2p.
Step 5: Place 2 electrons in the 2s sub-level, so we write 2s2.
Step 6: Now we have used 4 electrons (2 in 1s and 2 in 2s). We have 4 electrons left to place in the 2p sub-level.
Step 7: Place 4 electrons in the 2p sub-level, so we write 2p4.
Step 8: Combine all the parts together to get the full electron configuration: 1s2 2s2 2p4.
