What is valence electrons configuration?
Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen’s valence electrons as 2s²2p⁴.

What is gold’s atomic structure?
The arrangement of atoms in gold follows what’s called a “face centred cubic” (fcc) structure. Put simply, the atoms in gold form cubes, with an atom at each of the corners, and another atom in the centre of each of the faces (you can see what this looks like in the image below).
Why does gold have a different electron configuration?
It has a xenon core, plus a 4f outer core. Surprisingly enough, due to scalar relativistic effects (gold’s 1s electron moves at 57.7% the speed of light), its 6s electron contracts and its 5d and 4f orbitals expand, so that despite having one valence electron, gold is not very reactive.
How do you write valence shell configuration?
Write the valence electron configuration of each element by first indicating the filled inner shells using the symbol for the nearest preceding noble gas and then listing the principal quantum number of its valence shell, its valence orbitals, and the number of valence electrons in each orbital as superscripts.
