What is a man-made radioactive element first synthesised in a cyclotron around 50 years ago?
The answer is Berkelium.
How do you put radioactive into a sentence?
The radioactive element was observed by many scientists around the world.
How would you find the age of a fossil?
You can use relative dating which is looking at the rocks around it, or you can use radiometric dating, which compares the amount of radioactive element with the amount of nonradioactive element in the rock.
Is Mercury unstable and also radioactive?
Mercury is a stable element, meaning it does not naturally undergo radioactive decay. However, certain isotopes of mercury can be radioactive if they are artificially produced in a lab. Overall, mercury is known for its liquid form at room temperature, high toxicity, and ability to form amalgams with other metals.
Where do nuclear decay occur naturally?
Radioactive Decay occurs naturally all around us. If you test for radiation with a Geiger Counter, you will find that it picks up radiation in the air around you. Mostly, however, radioactive decay occurs in the earth's crust. I cannot name a specific element, as there are many that decay.
Why do home smoke detectors contain radioactive materials?
the bottom line is that when smoke gets into the detector, it's electrical current is interrupted, causing the alarm to sound (which im guessing you already knew) I'm not totally sure why the radioactive element (americium-241) has to be in there, but what I DO know (contrary to what the previous poster put) is that the alpha rays produced by the radioactive element are NOT strong enough to escape, and therfore pose NO harm whatsoever to people around it.

What is the range of half-lives of different radioactive element?
It would be quite difficult to list all radioactive elements and their half lives in this area. Lithium 5 has a half life of about a trillionth of a second. Uranium 238 has a half life of about 4.7 billion years. Since the world is about 4.2 billion years, over half the Uranium 238 is still around. The first element in the Periodic Table, Hydrogen, has a radioactive form, Hydrogen 3. It has a half life of about Twelve and a half years. Helium has a radioactive form, Helium 5. It's half life is a trillionth of a second. Then you get to elements with different radioactive isotopes. You will need to look them up in a handbook. Tin is the element with the most isotopes.
Is Californium the same at room temperature?
Californium is a radioactive element with a half-life of around 2.6 years, and it decays through spontaneous fission. At room temperature, it would emit alpha particles and gamma rays as it undergoes radioactive decay. Due to its radioactivity, Californium is not stable and can be harmful to living organisms if mishandled.
Do lithium has the lowest electronegativity?
Lithium does not have the lowest electronegativity. It has an electronegativity of around 1.0 on the Pauling scale. Francium is typically considered to have the lowest electronegativity among the elements.
What is an every day use for Ununquadium?
Ununquadium is a radioactive, lab-produced element and has not yet been confirmed. It has such a short half-life that it wouldn't be around long enough for it to be much use. It has no use except for experimentation.
