Answer:
The first two electrons is placed in the 1s orbital. The next 2 electrons for magnesium go in the 2s orbital.The next six electrons will go in the 2p orbital. We’ll put six in the 2p orbital and then put the remaining two electrons in the 3s.Therefore, the Magnesium electron configuration will be 1s22s22p63s2.

Which element has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d6?

Thus, following the rules on how to fill the orbitals, the electronic configuration of iron (for example) is 1s2 2s2 2p6 3s2 3p6 4s2 3d6 , and it is abbreviated form [Ar] 4s2 3d6.
