What does the last element in any period always have?

Answer 1

A fully filled valence shell.

The final elements of each period are associated with group 18, which is the group of noble or inert gases. All of these gases are usually non-reactive because their valence shells are completely filled.

Answer 2

Period 1 elements always have their outermost electron shell fully filled with electrons, forming a stable electron configuration; for elements in all other periods of the periodic table, this is equivalent to having a full outermost electron shell, which contains two electrons in the case of helium.

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.
