The period of elements that are all radioactive?
All elements comprising the period 7 in the periodic table are radioactive. In total this period has 32 elements.
How do you use radioactive as an adjective in a sentence?
You can just put something in the sentence that is going to be radioactive that's all.
What planets and celestial bodies seem to be radioactive?
Stars seem to be, but they don't have big and/or unstable atoms such as most radioactive elements have. They release sub atomic units when their atoms fuse, along with rays such as gamma rays, which is why they can seem to be similar to other radioactive things. Some planets with atmostpheres that are ionised by ionising rays can also be similar to radioactive things perhaps.
Atoms with certain characteristics are radioactive Which is least likely to be radioactive?
all atoms with an atomic number under 40
How does nuclear power affect you daily?
it releases harmful radio active waves which s harmful to all living organism
Are creosote fumes harmful to humans?
yes all fumes are potentially harmful to humans
What is the problem with disposing of radioactive wastes is that they have a long what?
Radioactive substances have half-lives. This is because the isotope constantly is changing from the radioactive isotope to a daughter element. For example, eventually, when uranium's radioactivity is gone, it becomes lead. After one half life of a radioactive substance, only 50% of that substance is still radioactive. Therefore, after one half-life, a piece of uranium is 50% lead and therefore %50 less radioactive. After another half-life, it has 25% of the original radioactivity, and 75% of the original uranium has become lead. This is the problem with radioactive wastes. It takes many years just for one half lives for some substances, such as uranium. Because radioactivity is harmful, those substances have to be stored until they are no longer radioactive. So, in short, the problem with disposing of radioactive wastes is that they have long half-lives. (although this is not true with ALL substances because some have short half-lives, but, in general, radioactive substances have long half-lives.
Is alpha radiation emmitted by all radioactive substances?
no -s ome substances are just beta emitters etc
Is smoke poisonous or harmful?
There is no question that there are poisonous substances in all forms of smoke, and breathing it can be harmful.
Why is grasshopper harmful?
Grasshoppers are only harmful to vegetation such as plants and crops. They are not harmful to humans at all.
Is rutherfordium harmful?
Rutherfordium is a synthetic element and its properties are not well-studied. However, it is expected to be highly radioactive and potentially harmful due to its radioactive decay. As with other radioactive elements, proper safety measures and handling protocols should be followed to minimize the risk of exposure.
Is plankton harmful to humans?
Yes, plankton is harmful to humans because they carry salmonella disease. Other than that, they are not harmless at all.
Does all radioactive substances are manmade or artificial?
Radioactive elements both occur in nature (Uranium is the prime example) and are made through the works of man (Plutonium is man-made).
Only nonliving things are radioactive?
No. All things are radioactive, including living things and even humans. All matter (save a few) emits gamma radiation spontaneously.
What is radioactive element in chemistry?
Actimium, plutonium, radon, radium, thorium, uranium
What is the process by which some substances spontaniously emit radiation?
All elements with an atomic number >83 are naturally radioactive
Are radioactive materials dangerous Explain?
yeah! almost all radioactive materials are dangerous, from these material radioactive rays are originated which are namely alpha,beta,gamma and when these rays strike to the body so it leave incurable burn,however its small amount is also harmful such as: the radioactive material named radium are found in varieties of wrist watches so its also harmful for human health X-Rays are electromagnetic rays and these are also harmful but not so much therefore physicians avoids for X-rays reports but in severe condition they are compel to do that advise There are two type of radioactive element one is natural radioactive and other is artificial radioactive element From natural radioactive element radioactive rays are always originated so,radioactive materials are dangerous even it is artificial or natural
