Comparative Atomic Mass Table

The comparative atomic mass table provides information about the atomic masses of various elements. The atomic mass of an element is the average mass of the atoms in a naturally occurring sample of the element. It is expressed in atomic mass units (u) or daltons (Da).

Here is a comparative atomic mass table for some elements:

| Element | Atomic Mass (u) | |---------|----------------| | H | 1 | | He | 4 | | Li | 7 | | Be | 9 | | B | 11 | | C | 12 | | N | 14 | | O | 16 | | F | 19 | | Ne | 20 | | Na | 23 | | Mg | 24 | | Al | 27 | | Si | 28 | | P | 31 | | S | 32 | | Cl | 35.5 | | Ar | 40 | | K | 39 | | Ca | 40 | | Fe | 56 | | Ag | 108 | | I | 127 | | Ba | 137 |

Please note that the atomic masses listed in the table are approximate values and may vary slightly depending on the source.

I hope this information is helpful! Let me know if you have any further questions.
