1s2 2s2 2p2
The atomic number of zinc is 30. Its abbreviated electron configuration is [Ar]4s23d10 The full electron configuration is 1s22s22p63s23p64s23d10 (configurations for the atom in its ground state. Ions and excited atoms have different configurations).
Beryllium is located in group 2 of the periodic table and has a valency of two. It is an element in the 2nd period and has two main energy levels. Therefore the electron configuration is 1s2 2s2.
Silicon has 2 electrons in the 3p sublevel in its ground state. Silicon's full electron configuration is: 1s2 2s2 2p6 3s2 3p2.
The element silicon (atomic number 14) has the following electron configuration :- Full configuration: 1s2 2s2 2p6 3s2 3p2- Compressed (without all standard script numbers): 1s2 2s2p6 3s2p2- Noble Gas form : [Ne] 3s2 3p2 / [Ne] 3s2p2 (this works because [Ne] symbolizes the electronic configuration of Neon, which is 1s2 2s2 2p6. When added to 3s2p2, it is equivalent to the full electron configuration of Silicon, when neutral.)The electon configuration of silicon is 1s22s22p63s23p2. The abbrieviated electron configuration is [Ne]3s23p2.
The expected ground-state electron configuration of copper is ; however, the actual configuration is because a full dsubshell is particularly stable. There are 18 other anomalous elements for which the actual electron configuration is not what would be expected.
