Answer 1

Answer 2

Potassium, Titanium, and Bromide are all on the same row, or period, of the periodic table

They are on the 4th period, and therefore have 4 orbitals

Answer 3

However, if you look at the positioning of Carbon, you can see that it is on a different period. It is on the 2nd period.

Therefore, we know that Carbon only has 2 orbitals. Hope this was helpful!

Answer 4

It really does help to reference a periodic table when doing problems like these :)
