Answer:
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 <em>-By Aufbau principle-</em>
For Ti²⁺, the ground state electron configuration is removing the 3d² electrons.
That means that ground state electron configuration for Ti²⁺ is:
<em>d. [Ar] 4s²</em>
<em></em>

Answer:
Explanation:
Hello,
Percent composition is defined as:
%
Whereas is the subscript in the formula, the atomic mass of the ith element and the compound's molecular mass, thus, solving for :
Now, divining each over the least one () we get:
Finally the empirical formula turns out into:
