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 else can I help you with?
What does it means an element is radioactive?
It means the element is unstable and gives off dangerous particles.
What does it mean if an element it radioactive?
this is because an element is sometimes never radioactive but one may be made just to be radioactive this is because an element is sometimes never radioactive but one may be made just to be radioactive
Is the element sodium radioactive or non-radioactive?
non radioactive element
If an element is radioactive is it's nucleus unstable?
Yes,The element is radioactive due to the instability of its nucleus.See the related question below for more information.
Why is uranium classified as a radioactive element?
That means that some of the atoms will decay over time.
How do you use radioactive element in a sentence?
A radioactive element is one that discharges radiation. Uranium is a radioactive element. A radioactive element is very dangerous if you don't have protective clothing. You should never go near a radioactive element.
What characterizes a radioactive element?
A radioactive element is characterized by having unstable atomic nuclei that decay and emit radiation in the form of alpha particles, beta particles, or gamma rays. This decay process results in the transformation of the element into a different element or isotope.
What is the breakdown of a radioactive isotope of the same element or of another element?
radioactive decay
What element is a radioactive element?
The radioactive element is composed of unstable nuclei that try to reach stability through emitting nuclear radiations as alpha, beta, and gamma nuclear radiations.
Radioactive decay occurs when atoms of an unstable element?
It means that massive nuclei break apart.
Can an element be broken down into other substamces?
Yes, but not by chemical means, only by radioactive transmutation.
What is the best known radioactive element?
Probably uranium is the best known radioactive element.
