How do you know the number of electrons in the outermost energy level of an atom?
Olivia AntonBased on the periodic table
You examine the element's group. This method is limited to groups 1, 2, 13, and 17.
Group 13 includes ex boron, which has three valence elevtrons (outermost level).
Since Florine belongs to group 17, she has seven electrons in the outermost level.

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.
