| But barium has an atomic number of 56, barely more than half that of uranium. |
| The higher the atomic number, the more shells and electrons an atom will have. |
| In such a case, an element's atomic number and atomic mass should be about equal. |
| Early in 1999 synthesis of the element with atomic number 114 was reported. |
| When assigning priority to groups, atoms that are directly bonded to the carbon atom have their priority based upon their atomic number. |
| The transfermium elements are those elements with atomic numbers greater than 100, the atomic number for fermium. |
