Chemical elements are the basic building blocks of matter. Elements are referred to by name and by their symbols, to make it easier to write chemical structures and equations. Here are 20 examples of elements and their symbols and their number on the periodic tableĀ (in case 10 wasn't enough for you).

There are 118 elements, so if you need more examples, here is the full list of elements.

1 - H - Hydrogen
2 - He - Helium
3 - Li - Lithium
4 - Be - Beryllium
5 - B - Boron
6 - C - Carbon
7 - N - Nitrogen
8 - O - Oxygen
9 - F - Fluorine
10 - Ne - Neon
11 - Na - Sodium
12 - Mg - Magnesium
13 - Al - Aluminum
14 - Si - Silicon
15 - P - Phosphorus
16 - S - Sulfur
17 - Cl - Chlorine
18 - Ar - Argon
19 - K - Potassium
20 - Ca - Calcium

Notice the symbols are one- and two- letter abbreviations for their names, with a few exceptions where symbols are based on old names. For example, potassium is K for kalium, not P, which is already the element symbol for phosphorus.
