Electronic configuration of Elements is the distribution of electrons within the orbitals of its atom which relates to its chemical and physical properties.
Abbreviated Electronic Configuration: starts from the last noble gas electronic configuration before you reach the element you are trying to write.
Unabbreviated Electronic Configuration: starts from the very beginning of the periodic table and continues all the way to your element. It is much longer and more time-consuming.
Electronic configuration of gold
Since Gold is a neutral atom and the atomic number for GOLD is 79.
The unabbreviated electron configuration for GOLD is
1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p6 4f14 5d10 6s1
