Question

What electron configuration represents Titanium (Ti)?

A. 4,4
B. 2,8,8,4
C. 2,8,4
D. 2,8,22

Answer 1

I believe it is B. 2.8.8.4

Answer 2

B. 2,8,8,4

Step-by-step 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
