What electron configuration represents Titanium (Ti) ?

A. 4,4

B. 2,8,8,4

C. 2,8,4

D. 2,8,22

I believe it is B. 2.8.8.4

B. 2,8,8,4

Explanation:

Atomic number of Titanium: 22

Then, it has 22 electrons. From the periodic table, we can see that they are distributed as follows:

first shell: 2 electrons second shell: 8 electrons third shell: 8 electrons fourth shell: 4 electrons

total: 2 + 8 + 8 + 4 = 22 electrons

We also know that it has four shells because it is located at the 4th period in the periodic table
