Here's how it works:
* [Xe] represents the electron configuration of the noble gas Xenon, which is the closest noble gas to mercury on the periodic table. This is a shorthand way of indicating the filled inner shells.
* 4f14 indicates that the 4f subshell is completely filled with 14 electrons.
* 5d10 indicates that the 5d subshell is completely filled with 10 electrons.
* 6s2 indicates that the 6s subshell has 2 electrons.
This shorthand notation efficiently describes the electron configuration of mercury in its ground state, emphasizing the filled shells and subshells that contribute to its stability.
