How do you determine what group number an element is in?
Owen AmbroseThe group numbers should be at the top of each group on the periodic table.
The periodic table usually has each group numbered at the top. There are 18 groups from left to right. An older system which is still in use uses Roman numerals and A or B.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
