How would you distinguish an isotope from a neutral element?
1. An atom is neutral because hasn't an electrical charge. 2. An ion has an electrical charge, positive or negative.
What element was named for Marie and Pierre Currie?
radioactivity,polonium,uranium,and radium.
How do you determine the radioactive decay of an element?
The radioactivity of the materials is measured with suitable instruments.
What are the differences between natural radioactivity nd artificial radioactivity?
Natural Radioactivity arises from radioactive components contained in nature. Artificial Radioactivity will come through element produced with in nuclear reactors as well as accelerators. Natural Radioactivity is a spontaneous process of disintegration. Artificial Radioactivity is carried in synthetically produced radioactive elements used in nuclear reactors.
How is half time used on an element?
If you mean HALF LIFE, that is the length of time it takes a quantity of a radioactive element to lose half its radioactivity.

Is uranium the first radioactive element?
Radioactivity is discovered on uranium.
Is an element's atomic mass always indicative of its level of radioactivity?
no
What is it called when an atom decays and become another element?
Radioactivity
Where does the element californium come from?
It is a man-made element and, due to its high radioactivity does not exist in nature.
What is property in which unstable nuclei of an element spontaneously emit radiation?
Radioactivity
Is bombardment of alpha particles on beryllium artificial radioactivity?
You can say that as long as the alpha particle itself is not originating from a radioactive element. If however one is able to isolate the helium nucleus from the elemental atom and then used for bombarding towards the beryllium then it is considered as an example of artificial radioactivity. Or the production of a radioactive element(synthetic element) like Francium can be considered artificial radioactivity.

When elements are formed by another element why is it dangerous?
The process where an element turns to another is radioactive decay, and exposure to radioactivity is dangerous.
