Q
Q: What is the electron configuration of a neutral oxygen atom?
Solution:
Oxygen has 8 electrons, and its electron configuration is 1s2 2s2 2p4.
Steps: 6
Show Steps
Step 1: Understand that a neutral oxygen atom has 8 electrons.
Step 2: Electrons are arranged in energy levels or shells around the nucleus.
Step 3: The first energy level can hold a maximum of 2 electrons. So, we fill this level first: 1s2.
Step 4: The second energy level can hold a maximum of 8 electrons, but we only need to fill 6 more for oxygen. We fill the 2s sublevel next: 2s2.
Step 5: Now we have 4 electrons left to place in the 2p sublevel. We fill this sublevel: 2p4.
Step 6: Combine all the filled sublevels to write the complete electron configuration: 1s2 2s2 2p4.
