Many isotopes are very unstable and can exist in that form for only a very short time; others can last billions of years. Gold has 40 known isotopes, and another 20 not yet seen but theorized by ...

Stable isotopes do not decay into other elements. In contrast, radioactive isotopes (e.g., 14C) are unstable and will decay into other elements. The less abundant stable isotope(s) of an element have ...

Read our explainer to find out how isotopes can help experts understand more about water resources, atmospheric pollution, and the geographical and botanical provenance of food. Unstable isotopes, ...

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

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 ...

Supply agreements and reservations for specific isotopes and delivery schedules are currently available. Nusano is also hosting invitation-only preview events of its production facility. Customers ...
