Periodic Table of elements
| Name | Symbol | Atomic Number | Atomic Mass | Group | Period |
|---|---|---|---|---|---|
| Actinium | Ac | 89 | [227]The element does not have any stable nuclides, and a value in brackets, e.g. [209], indicates the mass number of the longest-lived isotope of the element. However, three elements, Thorium, Protactinium, and Uranium, have a characteristic terrestrial isotopic composition, and thus their atomic mass given. | 7 | |

| Americium | Am | 95 | [243] | 7 | |
| Antimony (Stibium) | Sb | 51 | 121.760(1)The isotopic composition of this element varies in some geological specimens, and the variation may exceed the uncertainty stated in the table. | 15 | 5 |
| Argon | Ar | 18 | 39.948(1) The isotopic composition varies in terrestrial material such that a more precise atomic weight can not be given. | 18 | 3 |
