The atomic number of an element is determined by the number of protons in its nucleus, which is also equal to the number of electrons in a neutral atom.

The electronic configuration given is [Ar]3d5. The [Ar] represents the electron configuration of Argon, which has an atomic number of 18.

The 3d5 means there are 5 electrons in the 3d orbital.

So, to find the atomic number of the element X, you add the atomic number of Argon (18) to the number of electrons in the 3d orbital (5).

18 + 5 = 23

Therefore, the atomic number of element X is 23.
