The nucleus of each atom contains protons and neutrons. While the number of protons defines the element (e.g., hydrogen, carbon, etc.) and the sum of the protons and neutrons gives the atomic mass, ...

Researchers at the Accelerator Laboratory of the University of Jyväskylä, Finland, measured very precisely atomic masses of radioactive lanthanum ...

A radioactive isotope's nucleus is unstable and spontaneously decays, giving off radiation and changing into a different isotope. The rate at which nuclei decay is constant. Half-life describes ...

Key fact Isotopes are forms of an element that have ... neutrons A = 64 Number of neutrons N = 64 - 30 = 34 Since this is a nucleus there are no electrons There are 30 protons and 34 neutrons.

Researchers at CERN have made a significant breakthrough in nuclear physics by uncovering strong evidence that Tin-100 (100 ...

A research team has discovered another piece in the puzzle of the formation of the Moon and water on Earth. The prevailing theory was that the Moon was the result of a collision between the early ...

A research team from the University of Göttingen and the Max Planck Institute for Solar System Research (MPS) has discovered another piece in the puzzle of the formation of the moon and water on Earth ...

This Section implements all activities of the IAEA's Water Resources Programme, which promotes and transfers know-how on the use of isotope hydrology as an effective tool for water resources ...

Isotope: Variants of a particular chemical element ... which is related to the distribution of charge within the nucleus. Electric Quadrupole Moment: A measure of the distribution of charge ...

Stable isotopes are non-radioactive forms of atoms. Although they do not emit radiation, their unique properties enable them to be used in a broad variety of applications, including water and soil ...
