Are radioactive elements made in a laboratory?
What an interesting question. The answer is however complex.It is possible to make small amounts of some radioactive elements or radioactive isotopes of some elements in a laboratory (usually involving a nuclear pile or an accelerator). For instance the element Plutonium is made this way.(Other radioactive elements are produced naturally by the radioactive decay of heavier radioactive elements)However, making a radioactive element or isotope from scratch requires the application of an enormous amount of energy. The place where all elements heavier than the element Iron (Fe - Atomic number 26) are made is in stellar explosions, the death of stars 8 or more times more massive than our Sun, called "supernovas".It is in supernova explosions that the radioactive elements are made.

radioactive elements
What are elements with no stable isotopes called?
Radioactive.
When radioactive isotopes break down into other elements the process is called?
radioactive decay
What are the objects in a set called?
A set is a collection of objects called ELEMENTS OR MEMBERS.
What family is made up of radioactive elements?
This family is called, after IUPAC nomenclature -- actinoids.
What are unstable elements that give off energy as they decay called?
The elements described are said to be radioactive.
What are the radioactive elements with atomic number from 90 to 103 called?
The Actinides.
Which elements posses only one electron in their valence shell and what are they called and what is the radioactive element of this group?
These are the alkali metals; the radioactive one is francium (Fr).
What is special about all the elements beyond uranium on the periodic table?
These elements are called transuranic elements.
What are the radioactive elements with atomic number from 90 to 103 in the periodic table called?
Actinide Series.
What is it when naturally unstable elements realize particles?
This phenomenon is called radioactive disintegration.
What elements give off particles?
the unstable elements in periodic table is Radium because it always leave the radio active waves so it lost its mass slowly slowly all radio active elements are unstable. Any thing more By Varun
