Can an element be separated into simpler materials except during nuclear reactions?
No, an element cannot be separated into simpler materials through chemical means, as it is defined as a pure substance consisting of only one type of atom. Chemical reactions can change the arrangement of atoms but do not alter the elemental identity. The only way to break down an element into simpler components is through nuclear reactions, which can change one element into another by altering its atomic structure.

Is is possible to convert atoms of one element into atoms of another?
According to Dalton's atomic theory chemical reactions occur when atoms are separated, joined, or rearranged. Atoms of one element, however, are never changed into atoms of another element as a result of a chemical reaction (it is possible only during nuclear reactions and radioactive disintegration).
All nuclear reactions due to nuclear transmutation?
Nuclear reactions may or may not involve nuclear transmutation. We need to split hairs here to arrive at the correct answer, and the answer involves the definition of the word transmutation. We sometimes think of transmutation as the changing of one element to another. Fission and fusion reactions do this, and many kinds of radioactive decay also convert one element into another. But there are some kinds of nuclear reactions that do not change an atom from one element to another, but instead change it from one isotope of a given element into another isotope of that element. There are a number of examples of this, and one is where isotopes of a given element absorb a neutron and become another isotope of that element. A given nucleus incorporates the neutron into its nuclear arrangement and the next heavier isotope of that element is created. If a "strict" definition of transmutation is used where it means a nuclear reaction that changes one element into another, then no, this does not always happen as illustrated above with the example of neutron absorption. If a more general interpretation of the term is used where we say that the nucleus transmutes meaning changes configuration, then yes, nuclear reactions involve nuclear transmutation.
What is the modern source of the roentgenium element?
Roentgenium is an artificial element, obtained via nuclear reactions in particle accelerators.
Do nuclear chain reactions happen in only uranium?
No, nuclear chain reactions can happen in several types of fissile materials, not just uranium. Other examples include plutonium and thorium. These materials can undergo fission reactions and sustain a self-sustaining chain reaction.
What is the of lawrencium's origin?
Lawrencium is an artificial chemical element obtained by nuclear reactions in linear accelerators.
What element can be separated into simpler materials?
No element can be separated into simpler materials; the constituent parts of atoms (protons, neutrons, and neutrons) can not constitute stable materials by themselves, but only in combinations with some of the other constituents.
Transmutation reactions can occur when the?
In nuclear science, transmutation is where one chemical element or isotope is converted into another. It occurs when materials decay, or it can be caused by nuclear reaction.
Is is possible to convert atoms of one element into atoms of another?
According to Dalton's atomic theory chemical reactions occur when atoms are separated, joined, or rearranged. Atoms of one element, however, are never changed into atoms of another element as a result of a chemical reaction (it is possible only during nuclear reactions and radioactive disintegration).
How did protactinium come in existence?
1. Protactinium is a natural chemical element; protactinium can be separated from uranium ores. 2. Protactinium can be obtained by nuclear reactions from thorium 232.
How are the materials in plutonium mined?
Plutonium is not typically mined; rather, it is produced artificially in nuclear reactors through the irradiation of uranium-238. The uranium undergoes a series of neutron capture reactions to become plutonium-239, which can then be chemically separated.
Is a new material new materials?
No materials are made from nuclear reactions in stars
What is the process where in a nuclear reactions of atom are being transformed into atoms of simple element?
nuclear fission

What are the occurrences of the element nobelium?
Nobelium is an artificial element; it is prepared only by nuclear reactions in accelerators.
Californium where it came from?
Californium is an artificial element obtained by nuclear reactions.
What are nuclear materials?
Nuclear materials refer to substances that can undergo nuclear reactions, such as uranium and plutonium. These materials are used in nuclear power plants to generate electricity or in nuclear weapons for military purposes. Special precautions are needed in handling and storing nuclear materials due to their radioactive properties.
What element was being used in Chernobyl?
The Chernobyl disaster involved the release of radioactive materials, specifically radioactive isotopes of iodine, cesium, and strontium, which are byproducts of nuclear fission reactions.
