Core label represents the fixed nuclear charge; individual neutrons are not inferred from standard atomic weight.
Reviewed atomic properties
Unavailable measurements remain explicitly unavailable.
First ionization energy890.1 kJ mol⁻¹
Covalent radius136 pm
Electronegativity2.54 Pauling
Relativistic contraction of the 6s orbital shifts gold’s absorption into the blue, which is why it looks yellow rather than silver.
Description of this simulation
Gold is neutral here: 79 protons are balanced by 79 electrons across shells 2, 8, 18, 32, 17, 2.

What this model shows — and what it simplifies
Educational ModelThe nuclear charge stays fixed at 79 protons, which is what defines Gold.
Where do we see this in real life?
The electron count and measured properties of Gold help determine how it bonds, reacts and is identified in chemical materials.
