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 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.
Why an element call radioactive?
it is unstable and decays to another element
What do you mean by radioactive element?
An element that has an unstable nucleus and therefore emits alpha, beta and/or gamma radiation.
What best describes a radioisotope?
its nucleus is unstable
What do you mean by radioactive?
An element that has an unstable nucleus and therefore emits alpha, beta and/or gamma radiation.
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.
When an unstable isotope produces a particle and energy it can change the number of protons in the nucleus. This creates?
An atom of a different element.
What makes a nucleus unstabe?
A nucleus with too few nuetrons is unstable because there are not enough to keep the protons. There must be a certain amount of nuetrons for every element.
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 aspects of the composition of a nucleus can cause it to be unstable?
The two aspects that cause the nucleus of any element atom to be unstable are:not have the specific neutron/proton ratio to be a stable nucleus, and orhaving number of protons that exceeds the stability limit (exceeding 83).Referring to question below for more information.
