What is the electron configuration of erbium?
Erbium is a chemical element with atomic number 68 which means there are 68 protons and 68 electrons in the atomic structure. The chemical symbol for Erbium is Er. Electron configuration of Erbium is [Xe] 4f12 6s2. Possible oxidation states are +3.
What is the electron configuration for copper?
This would make the electron configuration for copper, 1s22s22p63s23p64s23d9 or in noble gas configuration [Ar] 4s23d9. However, because the 3d orbital is so much larger then the 4s orbital and the 3d orbital only needs one more electron to be filled, the 3d orbital pulls an electron from the 4s orbital to fill this empty space.
How many electrons are in the 2s orbital of copper?
Since 1s can only hold two electrons the next 2 electrons for Copper go in the 2s orbital. The next six electrons will go in the 2p orbital. The p orbital can hold up to six electrons. We’ll put six in the 2p orbital and then put the next two electrons in the 3s.
