What element family have no radioactive elements?
Radioactive elements exist in all groups of the periodic
As radioactive element is an element that is on the Priodic Table of Elements. A Radioactive Element is usually radioactive.
Actinium (Ac) is a chemical element. Actinoids is the name of the radioactive elements family which contain actinium.
Yes, but only if it is radioactive. Radioactive elements change into different elements through radioactive decay.
The element Bismuth (Bi) belongs to the Nitrogen family (Group 15). This means it has similar characteristics to other elements in this family. Bismuth is atomic number 83 and the last non-radioactive element.
Uranium comes from the (radioactive) actinoids family, period 7. Uranium is a metal.
A chemical element is radioactive if this element emit radioactive radiations as alpha, beta or gamma; all artificial elements or isotopes are radioactive.
All the elements from atomic number 84 [Polonium (Po)]and onwards are radioactive. Also, elements with atomic numbers 43 and 61 (Technetium and Promethium) are radioactive. If an element is radioactive, it means it's nucleus is likely to decay into another element.
All elements after lead (Pb) on the periodic table are radioactive. Isotopes of lighter elements (C-14 for example) can be radioactive as well. And, in fact, all elements have radioactive isotopes.
Answer There are actually quite a few radioactive elements. As a rule, everything with an atomic mass greater than lead is radioactive. Isotopes of lighter elements can also be radioactive. Answer All elements have radioactive isotopes. Many of these are found in nature. Potassium-40 is particularly common.
Polonium is often considered to be the most radioactive element, but there are far more radioactive elements like nobelium and lawrencium. However, the most radioactive elements are man-made like ununtrium and ununseptium. Out of these, ununoctium is the most radioactive but scientists are continuing to make even more radioactive elements today.
There is not one, but many radioactive elements. Radioactive isotopes, to be more precise - because sometimes, one isotope may be stable, while another isotope of the same element is radioactive. All, or most, elements have radioactive isotopes.
Any element with atomic number 95 (Americium [Am]) or upwards is synthetic. A synthetic element is an element that was never or is no longer naturally occuring. All the currently synthesised elements are radioactive, but not all radioactive elements are synthesised.
A radioactive element is an element subject to spontaneous degeneration of its nucleus accompanied by the emission of alpha particles, beta particles, or gamma rays. All elements with atomic numbers greater than 83 are radioactive. Naturally occurring radioactive elements include radium, thorium, and uranium. Several radioactive elements not found in nature have been produced by the bombardment of stable elements with subatomic particles in a cyclotron. (The Free Dictionary.com)
The actinides are radioactive
Lead is the last element on the periodic table that isn't radioactive. It is also the heaviest of the non-radioactive elements.
I not sure how the first radio active element was formed but when it release radiation it also release other radioactive elements. For example: the element actinium, radiates and releases thorium. thorium radiates and releases francium. all of these are radioactive elements.
Radioactive elements are one whose atoms spontaneously split up releasing particles and radiation. This also resulted in the element changing to a daughter element.
All elements have radioactive isotopes. Add a couple of hundred neutrons, and any stable element becomes radioactive. Technetium, promethium, and anything heavier than bismuth (element 83) will have radioactive decay. radio active elements can be uranium,radium,thorium,polonium,actinium etc.usually all elements of atomic number higher than 82 show radioactivity.
No. Only radioactive elements, which undergo radioactive decay can change to different elements.
Yes, radioactive elements can change into other elements. For example, if Plutonium is splitted is becomes iron and other metalic element.
Radioactive elements are not used in the treatment of AIDS.
Relative dating - Absolute dating ... Radioactive elements
All elements have at least some radioactive (unstable) isotopes. But usually an element is only considered radioactive if all of its isotopes are unstable. The radioactive isotopes of the"non radioactive" elements are generally rare.
Most radioactive elements when kept in dark will glow to some extent. Radium could be thought of the highest glowing radioactive element out of all. Radioactive elements undergo spontaneous emission of either alpha, beta particles or gamma rays
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… Read More
Elements 89-112 are radioactive elements.
Answer Radioactive means unstable, so any element that has an unstable nucleus is radioactive. This is especially true of element's isotopes.
Radioactive elements always emit hazardous radiations.Lead metal absorbs these radiations .Hence we put any radioactive element in a lead chamber.
Period sever on the periodic table contains all the radioactive elements. Iron, in period 6, is the last stable element on the table, before the radioactive elements.
All elements after element number 83 (bismuth) have only radioactive isotopes. The only two lighter elements that have this property are element 43 (technetium), and element 61 (promethium). *Bismuth-209 is technically radioactive, but with a half-life of 20 billion billion years (2 x 1019 yrs).
Radioactive elements are used to date the age of rocks. Radioactive elements decay according to a known pattern. Scientists can use the elements of that pattern to determine when the rock with the original radioactive element was formed.
All the three elements are generally non-radioactive.
Mendelevium is a radioactive element. Generally radioactive elements are dangerous.
Uranium is a heavy chemical element; this type of elements are unstable and generally radioactive.
These are radioactive elements as uranium, thorium, promethium, plutonium, berkelium, etc.
Polonium is in the chalcogen family but is commonly said as the oxygen family. - Polonium is in the 16th group of the periodic table - Polonium is a metalloid - Polonium is a natural radioactive chemical element Group 16 (chalcogens) in the Mendeleev table of elements; the chalcogens are: O, S, Se, Te Po.
A stable element is any non-radioactive element. All elements before element atomic number 84 (not including 84) - Polonium (Po) are stable elements.
No the element Mercury is not Radioactive. None of the mercury ordinarily found in nature is radioactive. Like all elements, there are synthetic radioactive isotopes of mercury.
Yes. Francium is radioactive. All elements higher than lead, and some less than lead, are radioactive.
The Curies discovered two radioactive elements: polonium and radium.
This is an element (more exactly an isotope) which is not radioactive.
Lanthanides and Actinides probably
lanthanide elements: promethium Transition: technetium
Because these radioactive elements were obtained artificially, they are man made.
The Actinide series.
When elements such as uranium and plutonium decay do they form different elements chemical reactions or larger compounds?
When an element "decays", it forms a different element. This is the definition of "decay" when referring to radioactive elements.
Yes. Any element which is radioactive may bond together with other molecules and atoms, just as much as any other non-radioactive element. However, radioactive elements would have a slightly greater pull towards their bonded species if their nucleus has more neutrons than what is normal for non-radioactive elements.
All the elements from atomic number 84 onwards are radioactive and therefore unstable. They will all be part of radioactive decay chains.
All or almost all elements have radioactive isotopes if artificial isotopes are included. Among the naturally occurring elements, uranium, polonium, radium, and thorium have naturally occurring radioactive isotopes on earth.
