Solution

Solution Steps

Step 1: Understanding the Question

The question asks for the electron configuration of tungsten (W). Tungsten has an atomic number of 74, which means it has 74 electrons.

Step 2: Writing the Electron Configuration

To determine the electron configuration, we need to fill the electron orbitals in the order of increasing energy levels, following the Aufbau principle, Hund's rule, and the Pauli exclusion principle.

Step 3: Filling the Orbitals

The order of filling the orbitals is as follows:
