Name the orbitals which get filled in moving from left to right in fourth period

Explanation

To answer the question regarding the orbitals that get filled as we move from left to right in the fourth period of the periodic table, we can break it down step by step:

### Step 1: Understand the Periodic Table Structure
The periodic table is organized into periods (rows) and groups (columns). Each period corresponds to the filling of different electron orbitals.

**Hint:** Recall that each period corresponds to the principal quantum number (n) of the electrons being added.

### Step 2: Identify the Fourth Period
