When will an unstable nuclide stop emitting radiation?
An unstable nuclide will stop emitting radiation when it decays into a stable daughter nuclide. This decay process continues until a stable configuration is reached, which may take seconds to billions of years depending on the nuclide.

Is nickel a stable element?
Yes, nickel is a stable element. It is a naturally occurring element with multiple stable isotopes, such as Nickel-58, Nickel-60, and Nickel-62. It is commonly used in various industrial applications due to its stability and conductivity.
Why do we say that some elements aren't naturally occurring?
Some elements are not naturally occurring because they are created in laboratories through nuclear reactions or particle accelerators. These synthetic elements do not have stable isotopes and decay rapidly, making them difficult to find in nature. Examples include elements beyond uranium on the periodic table.
What is an isotope of 39K?
An isotope of 39K is potassium-39. It is a stable and naturally occurring isotope of potassium. It makes up about 93% of all naturally-occurring potassium.
What is the nuclide symbol for bromine-81?
81Br is one of the stable isotopes of bromine.
What is the correct nuclide symbol for bromine-81?
81Br is one of the stable isotopes of bromine.
Naturally-occurring strontium ion has a charge of?
Naturally-occurring strontium ions typically have a charge of +2. This is because strontium, which is an alkaline earth metal, loses two electrons to achieve a stable electronic configuration, resulting in the Sr²⁺ ion.
Is gallium a naturally occurring isotopes?
Yes, gallium does have naturally occurring isotopes. The most common stable isotopes of gallium are gallium-69 and gallium-71, with gallium-69 being more abundant at about 60% and gallium-71 about 40%.
What is an activation analysis?
An activation analysis is any of several techniques in which a subatomic particle or gamma ray is capture by a nuclide to form a second stable nuclide which is then measured.

What is the lightest element without a stable isotope?
The lightest element without a stable isotope is Technetium (atomic number 43). All of its isotopes are radioactive, with none occurring naturally on Earth.
