Why do electrons enter 4s before 3d?

We say that the 4s orbitals have a lower energy than the 3d, and so the 4s orbitals are filled first. We know that the 4s electrons are lost first during ionization. The electrons lost first will come from the highest energy level, furthest from the influence of the nucleus.

Is 1s2 2s2 2p6?

The electron configuration for Copper (Co) is: 1s2 2s2 2p6 3s3 3p6 4s2 3d7.

Which ions would have the electron configuration 1s2 2s2 2p6?

Oxygen has the electron configuration 1s2 2s2 2p6. When oxygen reacts to form ionic compounds, it completes its octet by gaining two electrons from the element it reacts with. These two electrons add to the p orbital of oxygen, giving it the electron configuration (1s2 2s2 2p6 ) of neon.
