[Xe] 4f¹⁴ 5d⁴ 6s²

Here's how to understand this:

* [Xe] represents the electron configuration of the noble gas Xenon (Xe), which is the closest noble gas to tungsten on the periodic table.

* 4f¹⁴ 5d⁴ 6s² represents the remaining electrons in tungsten's electron configuration, beyond those of xenon.

This notation is a shorthand way to represent the electron configuration of an element, emphasizing its relationship to the noble gases and making it easier to understand its chemical properties.
