What is An unstable isotope is called what?
It isn't really an ELEMENT that is unstable, but an ISOTOPE. That means that in general, for the same element, some atoms will decay, and some will not - the difference being the number of neutrons in the nucleus.
What terms best describes the nucleus of a radioactive element?
unstable
What is the process by which an element slowly decays over time?
It is through radioactive decay that a quantity of an unstable element will decay over time. A material that is unstable will undergo this process, and the sample is said to be radioactive.
What is an unstable nucleus that starts a decay process called?
A nucleus that starts to decay is called a radioactive nucleus or atom. It decays with a known and unique half life by several processes including but not limited to beta decay, alpha decay, electron capture decay, and positron emission.
Atom with an unstable nucelus is called?
It is a radioactive element.

What best describes a radioisotope?
its nucleus is unstable
What do you call an element with unstable nucleus?
Radioactive isotope, or radioisotope.
What terms best describes the nucleus of a radioactive element?
unstable
What are the characteristics of a atom?
A radioactive atom is an atom of an element with an unstable nucleus.
What do you mean by radioactive element?
An element that has an unstable nucleus and therefore emits alpha, beta and/or gamma radiation.
What makes an element unstable or radioactive?
The stability of an atom depends on a balance between the numbers of protons and neutrons in its nucleus and also on the total size of its nucleus; atoms with sufficiently large nuclei are inherently unstable. Please see the link.
What do you mean by radioactive?
An element that has an unstable nucleus and therefore emits alpha, beta and/or gamma radiation.
What it means when an element is radioactive?
Radioactive elements have unstable nucleii. When an unstable nucleus decays it emits energy in the form of electromagnetic waves and heavy particles and in the process forms new nucleii.
What is the process by which an element slowly decays over time?
It is through radioactive decay that a quantity of an unstable element will decay over time. A material that is unstable will undergo this process, and the sample is said to be radioactive.
What happens to a nucleus of an unstable atom?
An unstable nucleus can undergo radioactive decay to become more stable. This can involve emitting radiation in the form of alpha particles, beta particles, or gamma rays. The decay process results in a transformation of the nucleus into a different element or isotope.
What is an unstable nucleus that starts a decay process called?
A nucleus that starts to decay is called a radioactive nucleus or atom. It decays with a known and unique half life by several processes including but not limited to beta decay, alpha decay, electron capture decay, and positron emission.
