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.
When a net force changes an objects motion what is it called?
It is called acceleration.
What causes objects to move in a circle?
is called the centripetal force
What are elements in a bibliographic record called?
citation
What are the objects made by people long ago called?
Things made by humans long ago are called Artifacts.
What are elements with no stable isotopes called?
Elements with no stable isotopes are called radioactive elements. These elements spontaneously undergo radioactive decay, which leads to the formation of stable isotopes over time.
When radioactive isotopes break down into other elements the process is called?
radioactive decay
What family is made up of all radioactive elements?
The family of radioactive elements is called the Actinides. This group includes elements such as uranium, thorium, and plutonium, which are known for their radioactive properties.
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 elements that emit atomic particles are called?
Elements that emit atomic particles are typically referred to as radioactive elements. These elements undergo radioactive decay and emit particles such as alpha particles, beta particles, or gamma rays as they try to become more stable.
What are unstable elements that give off energy as they decay called?
The elements described are said to be radioactive.
Which are unstable elements that decay or break down into differt elements?
Unstable elements that decay or break down into different elements are called radioactive elements. These elements have an unstable atomic nucleus that undergoes radioactive decay, transforming into a different element and releasing energy in the process. Examples of radioactive elements include uranium, radium, and plutonium.
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.
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 are the radioactive elements with atomic number from 90 to 103 called?
The Actinides.
What are the radioactive elements with atomic number from 90 to 103 in the periodic table called?
The elements with atomic numbers from 90 to 103 are called actinides. These elements are known for being radioactive and having partially filled 5f orbital. They include well-known elements like uranium, plutonium, and americium.
