What does the color of each elements symbol represent?
It depends, but likely the type of element
In this periodic table (and in most), there is a key identifying what the colors mean.
Most commonly, the color represents what type of element it is (noble gas, alkali metal). This is not always true, as it could be:
- state of matter
- electronegativity
or something else. Look at the key if you are not sure.

The general category of an element is indicated by the color of its symbol on the periodic table; nonmetals are generally colored differently from 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.

- What is the molar mass of 1-butene?
- What do scientists call anything that takes up space and has mass?
- How does cooling the gases allows ammonia to be separated from unused hydrogen and nitrogen, and state what happens to these unused gases?
- Is chlorine a metal or a nonmetal?
- Copper is listed on the periodic table as having a relative atomic mass of 63.55. Reference books indicate two isotopes of copper, with relative masses of 62.93 and 64.93. What is the percent abundance of each isotope?
