Question

Gold (Au) should have an electron notation that ends in 6s24f145d9. To become more stable, the electrons in reality rearrange themselves. How do they do it

Answer 1

The electrons rearrange themselves to ensure that orbitals at lower energy levels are first filled before those at higher energy levels.

Electronic configuration

One of the rules of electronic configuration states that lower energy level orbitals are first filled with electrons before higher energy level orbitals.

Thus, the electrons in Gold will rearrange themselves to obey the above rule in order to achieve more stability.

Hence, the electronic configuration becomes: $4f^{14}, 5d^{10} ,6s^1$
