: First, let's find the atomic number of gallium (Ga) on the periodic table. : The electron configuration of an element can be determined by filling up the atomic orbitals according to the Aufbau principle, Pauli's exclusion principle, and Hund's rule. : For gallium, we start by filling the 1s orbital. : Next, fill the 2s and 2p orbitals. : Then, fill the 3s and 3p orbitals. : Gallium has 31 electrons, so we have 31 - 18 = 13 electrons left to place in the 4s and 3d orbitals. : Fill the 4s orbital with 2 electrons. : Finally, fill the 3d orbital with the remaining 11 electrons. The electron configuration of gallium (Ga) is $1s^{2} \ 2s^{2} \ 2p^{6} \ 3s^{2} \ 3p^{6} \ 4s^{2} \ 3d^{10}$.
