Choose the ground state electron configuration for ti 2 ⁺. a. [ar]4s23d4 b. [ar]3d4 c. [ar]4s23d2 d. [ar]4s2 e. [ar]3d2

d. [Ar] 4s²

Explanation:

The ground state electron configuration is the electron configuration of an atom with lower energy levels. The electron configuration for Titanium (Ti) is:

Ti = [Ar] 4s²3d² -By Aufbau principle-

For Ti²⁺, the ground state electron configuration is removing the 3d² electrons.

That means that ground state electron configuration for Ti²⁺ is:

d. [Ar] 4s²
