What made up all radioactive elements?
After disintegration all radioactive elements are transformed in other elements.
What element family have no radioactive elements?
Radioactive elements exist in all groups of the periodic table.
Can a natural isotope be radioactive?
Yes; some of the naturally occurring isotopes of the heaviest elements are radioactive.
What are the ten elements in thre periodic table that are radioactive?
all elements after uranium (atomic number 92) are radioactive.
Are all elements periodically change to become new element s?
No. Only radioactive elements, which undergo radioactive decay can change to different elements.
The period of elements that are all radioactive?
All elements comprising the period 7 in the periodic table are radioactive. In total this period has 32 elements.
Which group contains only radioactive elements?
The actinoids (formerly actinides) are all unstable metallic elements. The period 7 elements with atomic numbers from 89 (actinium, for which the group is named) through 103 comprise these elements. A link can be found below.
In what period do the elements in the actiniod series belong?
7th period.
Synthetic elements comprise a majority of which of the following groups?
Artifficial radioactive elements are situated in: - period 7 - actinoids (actinides) family
Radioactive elements comprise a majority?
Yes. Stable elements are 83 elements. all elements above that of atomic number 83 (Bismuth) are radioactive. Radioactive isotopes are of the order of 1500 radioactive isotope.
Do trace elements have to be radioactive?
No, trace elements are not necessarily radioactive. A link to a list of elements that have no natural radioactive isotopes is at a related question, below.
What made up all radioactive elements?
After disintegration all radioactive elements are transformed in other elements.
Are all transition elements are radioactive?
Not all of the transition elements are radioactive. Many of them are, and some of them have common radioactive isotopes, but some of them have no naturally occurring radioactive isotopes. Please note that all elements have synthetic radioactive isotopes, at least.
The pressure and heat that produces magma are caused in part by?
Radioactive elements
What families have no radioactive elements?
Radioactive elements exist in all groups of the periodic table.
What period on the periodic table of elements contains radioactive elements and what are they called?
it was found in 1896. you can not find them on the periodic table. you may find some, but often some are.
What element family have no radioactive elements?
Radioactive elements exist in all groups of the periodic table.
