Isotope methods determine the age of the Earth, help reconstruct the climate of the past, and explain the formation of the chemical elements in the Universe. This textbook provides a comprehensive ...

Both heavy and light stable isotopes participate freely in chemical reactions and in biological and geochemical processes, but the rate at which heavy and light stable isotopes react during physical ...

New nuclear reactor for medical isotope production comes online in east China's Zhejiang (Voice_over) One of China's nuclear reactors for medical isotopes is now officially online to produce ...

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 ...

Quantum tunnelling can at times be the cause of kinetic isotope effects, and in these cases conventional wisdom has been that molecules with isotopes of larger mass will react more slowly.

Electron shells are mentioned. Two extra neutrons are added to make an unstable isotope which explodes at the end. This clip could then be used to illustrate and introduce the concept of isotopes.
