The electron configuration of an oxygen atom is 1s² 2s² 2p⁴. Here's how we get to that:

1. The atomic number of oxygen is 8, which means an oxygen atom has 8 electrons.

2. According to the Aufbau principle, electrons fill the lowest energy levels first. So, the first two electrons go into the 1s orbital. We denote this as 1s².

3. The next two electrons go into the 2s orbital. Now we have 1s² 2s².

4. The remaining 4 electrons go into the 2p orbital. So, the final electron configuration of oxygen is 1s² 2s² 2p⁴.
