The electron configuration [Ar] 4s^2 3d^10 4p^1 corresponds to the element Indium (In), which is positioned after Gallium (Ga) in the periodic table. This configuration indicates that the element has a total of 49 electrons, as indicated by its position in the periodic table, given that Argon (Ar) accounts for 18 electrons, the 4s subshell contributes 2 more, the 3d subshell contributes 10, and the 4p subshell adds 1 electron.

Gallium has the electron configuration [Ar] 4s^2 3d^10 4p^0, indicating it has one fewer electron in the 4p subshell compared to Indium. Understanding the filling order of orbitals and the respective positions of elements in the periodic table provides clarity on how to identify the element corresponding to a given electron configuration accurately.

So, while it may initially seem that Gallium is the correct answer, the given electron configuration uniquely identifies Indium instead.
