| They also can form condensates out of numerous different elements, including sodium, potassium, lithium, cesium, hydrogen and helium. |
| They mapped the patterns made by known elements and discovered many new ones, including rubidium and cesium. |
| A second of time is defined as x oscillations of a cesium atom's resonant frequency, and is commonly measured in atomic clocks. |
| Researchers are particularly interested in zeolites filled with metal atoms such as cesium. |
| The alkali metals are silver colored except for cesium, which is pale gold. |
| The most accurate atomic clocks available today use the cesium atom and the normal magnetic fields and detectors. |
