WebThe first advance beyond the precision of caesium clocks occurred at NIST in 2010 with the demonstration of a "quantum logic" optical clock that used aluminum ions to achieve a precision of 10 −17. Optical clocks are a very active area of research in the field of metrology as scientists work to develop clocks based on elements ytterbium , mercury , … Web26 nov. 2024 · First Ionization Energy of Caesium is 3.8939 eV. Electron Affinity In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is added to the atom to form a negative ion. X + e– → X– + energy Affinity = – ∆H
