Can all elements be stable?
All radioactive elements are unstable. Most isotopes of elements in periodic table are radioactive. Overall, most of the elements are unstable but they are present in traces on earth. Most elements on earth are stable.
Can you find radioactive elements in a limestone mine?
It is unlikely to find naturally occurring radioactive elements in significant concentrations in limestone mines. However, trace amounts of natural radioactive elements like uranium and thorium may be present. For accurate information, it is recommended to conduct detailed geological surveys and analysis.
Which lanthanide element and which transition element have only radioactive isotopes?
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.
Why does the periodic table has over 110 elements when only 90 occur on earth?
The higher atomic number elements are radioactive and have long since decayed away (assuming they were here to start with).
Why transuranic element known synthetic elements?
Transuranic elements are known as synthetic elements because they are not found naturally on Earth and must be created in a laboratory through nuclear reactions. These elements have atomic numbers higher than uranium (92) and are generally unstable and radioactive. Scientists have been able to produce transuranic elements by bombarding heavy elements with particles to create new elements.
What alkaline earth metal is radioactive?
There are two radioactive alkaline earth metals: radium (Ra) and radium (Ra). Both elements have radioactive isotopes that undergo radioactive decay.
Radioactive elements comprise a majority?
Radioactive elements make up a small fraction of all naturally occurring elements in Earth's crust. Most elements are stable and non-radioactive. However, even though they are a minority, radioactive elements play important roles in various scientific, medical, and industrial applications.
Why is it hot in the earth's mantle?
Decay of radioactive elements in the mantle heats it.
Which alkaline earth metal is radioactive?
Radium. Elements with an atomic number greater than 83 are always radioactive.
What is the source of heating in the mantle?
Source of heat in mantle come from radioactive decay of the radioactive elements inside the earth..
Are all rare earth elements radioactive?
All rare earth elements except promethium have at least one stable isotope.Natural-abundance samples of lanthanum, cerium, neodymium, samarium, europium, gadolinium, erbium, ytterbium, and lutetium are all technically "radioactive" in that they contain measurable amounts of radionuclides, but the half-lives of these nuclides are mostly in the hundreds of millions of years or longer (in some cases much longer).
What is the source of heat in the mantle?
The source of heat in the mantle primarily comes from the decay of radioactive elements like uranium, thorium, and potassium. This process releases energy in the form of heat which contributes to the high temperatures within the Earth's mantle.
What elements is radioactive and synthetic barrium cesium currium and xenon?
Curium {Note correct spelling} is only element in the list given that is radioactive and synthetic.^ not correct answer and not even spelled right the correct answer is "lawrencium"The rare earth elements are located at the bottom of the periodic table and are comprised of the lanthanoid series and the actinoid series.The actinoid series is the second row of rare earth elements. All of these elements are radioactive, and all of these elements (except actinium, thorium, protactinium, and uranium) are synthetic.
Can all elements be stable?
All radioactive elements are unstable. Most isotopes of elements in periodic table are radioactive. Overall, most of the elements are unstable but they are present in traces on earth. Most elements on earth are stable.
Should sulfur dioxide be eliminated totally from the earth?
Practically this is impossible.
What 3 families contain no radioactive elements?
Oh, dude, let me break it down for you. So, the three families that contain no radioactive elements are the noble gases, the alkaline earth metals, and the alkali metals. It's like they're the cool kids who don't mess around with that radioactive drama. Just chillin' with their stable atomic structures, you know?
What different elements is the core of the earth made of?
Because of gravity, the Earth's inner layers consist of the heavy elements, mainly metals. The heavy and radioactive ones are the origin of most of the heat.
