The outer electronic configuration of the ground state chromium atom is `3d^(2),4s^(2)`.

Explanation

To determine whether the statement "The outer electronic configuration of the ground state chromium atom is `3d^(2), 4s^(2)`" is true or false, we will follow these steps:

### Step 1: Determine the Atomic Number of Chromium
Chromium (Cr) has an atomic number of 24. This means that a neutral chromium atom has 24 electrons.

### Step 2: Write the Electronic Configuration
We will write the electronic configuration of chromium by filling the orbitals according to the Aufbau principle, Hund's rule, and the Pauli exclusion principle.
