Here's how to determine the noble gas electron configuration for Tungsten (W):

1. Find Tungsten's Atomic Number:

* Tungsten has an atomic number of 74, meaning it has 74 protons and 74 electrons.

2. Identify the Preceding Noble Gas:

* The preceding noble gas is Xenon (Xe), which has an atomic number of 54.

3. Determine the Remaining Electrons:

* Tungsten has 74 - 54 = 20 electrons beyond Xenon's configuration.

4. Write the Noble Gas Configuration:

* The noble gas configuration for Tungsten is: [Xe] 4f¹⁴ 5d⁴ 6s²

Explanation:

* [Xe] represents the electron configuration of Xenon.

* 4f¹⁴ indicates that the 4f subshell is filled with 14 electrons.

* 5d⁴ indicates that there are 4 electrons in the 5d subshell.

* 6s² indicates that there are 2 electrons in the 6s subshell.
