What does the bold stair step line on the periodic table mean?
Avery AdamsDoes it represent the transition between metals, and non-metals?
The given table uses colours to separate metals, from semi-conductors such as silicon and germanium, and non-metals. As always, most elements on the Periodic Table are metals...

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.
