How do you find an atomic number?
The atomic number of an element is written in the box for each element on the periodic table. It will always be a whole number and they go in order from 1 to 118 in order.
As the example below indicates, the box for each element will always contain the atomic number, the name and symbol, and the relative atomic mass (atomic weight).
The example below lists the information in a different order. Most periodic tables have a key for reference.

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.
