The electron configuration for Argon (Ar), atomic number 18, is as follows:

1. The first energy level (n=1) can hold up to 2 electrons. So, we fill up the 1s orbital first. This gives us 1s².

2. The second energy level (n=2) can hold up to 8 electrons. We fill up the 2s orbital (2 electrons) and then the 2p orbital (6 electrons). This gives us 2s² 2p⁶.

3. The third energy level (n=3) can also hold up to 8 electrons. We fill up the 3s orbital (2 electrons) and then the 3p orbital (6 electrons). This gives us 3s² 3p⁶.

So, the full electron configuration for Argon is 1s² 2s² 2p⁶ 3s² 3p⁶.
