Einsteinium Half-Life
The half-life of the chemical element einsteinium (Es) is approximately 471 days, as reported by the International Union of Pure and Applied Chemistry. This means that if a sample of einsteinium has an initial amount of N atoms, after 471 days the number of remaining atoms will be N/2. The decay of einsteinium occurs through alpha emission, where the nucleus emits an alpha particle consisting of two protons and two neutrons. This process transforms the einsteinium nucleus into a new nucleus with atomic number two less than that of einsteinium, while the remaining four particles form an alpha particle that is emitted from the nucleus.
