To determine the atomic number of the element based on the given quantum numbers, we will follow these steps: ### Step 1: Identify the Principal Quantum Number (n) The principal quantum number \( n \) is given as 4. This indicates that the highest energy electron is in the fourth energy level. ### Step 2: Identify the Azimuthal Quantum Number (l) The azimuthal quantum number \( l \) is given as 1. This corresponds to the p-orbital (where \( l = 0 \) is s, \( l = 1 \) is p, \( l = 2 \) is d, and \( l = 3 \) is f). ...
