Radioactive decay occurs when?
When a radioactive element slowly turns into another element/s when it emits various particles.
What is the lightest element that can undergo radioactive decay and what type of decay occurs in that element?
The lightest "element" that can undergo radioactive decay is the isotope hydrogen-3, which undergoes beta decay. The lightest element with no radioactively stable isotopes is technetium, and its isotopes have different modes of decay.
How many protons are needed for a element to be naturally radioactive?
Whether an ISOTOPE (not element) is naturally radioactive depends not only on the number of protons, but also on the number of neutrons. For EVERY element, there are radioactive isotopes.There has to be a certain relationship between the number of protons and the number of neutrons, but the relationship isn't a simple one.
Which radioactive element has the symbol Ra?
Radium. Atomic number 88
What is the most radioactive thing?
Thorium, an element rarely found in some minerals.
Man made radioactive element first synthesised in a cyclotron around 50 years ago?
berkelium
What is a man-made radioactive element first synthesised in a cyclotron around 50 years ago?
The answer is Berkelium.
What was Man-made radioactive element first synthesised in a cyclotron around 50 years ago?
Berkelium
What element is FM?
The element with chemical symbol Fm is Fermium. Fermium is a Actinide Transition Metal and has 100 electrons in total. It is synthesised and highly radioactive.
What is a synthesized element?
Synthetic elements are unstable chemical elements not naturally found on the earth. They are synthesized in the laboratory. All of them are unstable and radioactive in nature, which means they emit radiations and decay into other elements.
Is curium manmade?
Yes, curium is an artificial, radioactive, chemical element. Discovered by Glenn T. Seaborg, Ralph A. James and Albert Ghiorso in 1944.
What is the 85th Element?
The element with atomic number 85 in the Periodic Table is Astatine (At). Astatine is the second radioactive element, but is not synthesised. It is part of the Group 17 - Halogens family. It has 85 electrons in 6 shells with 7 electrons in the outer shell.
What substance is found in mendelevium?
Mendelevium is a metallic radioactive element that is not found in nature; it therefore has to be synthesised. For example, it can be synthesised by bombarding einsteinium with alpha particles.Fermium, another metallic radioactive element - also not found in nature, has been produced by the radioactive decays of cyclotron-synthesised mendelevium.Note that radioactive decay is not a chemical phenomenon. Decay is the spontaneous process by which an atomic nucleus of an unstable atom loses energy by emitting ionizing particles or radiation. A decay results when an atom with one type of nucleus, called the parent radionuclide, transforms to an atom with a nucleus in a different state, or to a different nucleus containing different numbers of protons and neutrons. Either of these products is called the daughter nuclide. In some decays the parent and daughter are two different chemical elements, the decay process resulting in the creation of the new element (as with mendelevium decaying to fermium).Mendelevium is a chemical element. An element is a pure substance consisting of only one type of atom distinguished by its unique atomic number - the number of protons in its atomic nucleus.A chemical element is, thus, a substance that cannot be broken down or changed into another substance using chemical means.By definition:Mendelevium is a single and unique substance (an element) so, irrespective of its instability, noother chemical substance could be found in it..
What characterizes a radioactive element?
As radioactive element is an element that is on the Priodic Table of Elements. A Radioactive Element is usually radioactive.
Is the element sodium radioactive or non-radioactive?
non radioactive element
How do you use radioactive element in a sentence?
A radioactive element is one that discharges radiation. Uranium is a radioactive element. A radioactive element is very dangerous if you don't have protective clothing. You should never go near a radioactive element.
How is an element classiffied as a transuranium element?
Elements having more than 92 protons, the atomic number of uranium, are called transuranium elements.
