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 humans naturally radioactive?
No, humans are not naturally radioactive. While all living organisms contain trace amounts of radioactive elements, the levels are very low and not considered harmful.
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.
Why is grasshopper harmful?
Grasshoppers are only harmful to vegetation such as plants and crops. They are not harmful to humans at all.
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.
Is alpha radiation emmitted by all radioactive substances?
No, not all radioactive substances emit alpha radiation. Alpha radiation consists of helium nuclei (two protons and two neutrons) being emitted from the nucleus of an atom. Some radioactive substances emit alpha radiation, while others emit different types of radiation such as beta or gamma radiation.
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.
Introduction of radioactive?
Radioactive materials are substances that emit radiation in the form of particles or electromagnetic waves due to the unstable nature of their atomic nucleus. This radiation can be harmful to living organisms and can cause damage to cells and DNA. Radioactive materials are commonly used in medicine, industry, and research, but they need to be handled and disposed of carefully to minimize the risks associated with their radiation.
Are prokaryotes harmful to humans?
Some prokaryotes can be harmful to humans by causing infectious diseases, while others are beneficial and essential for processes like digestion. It is important to note that not all prokaryotes are harmful.
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.
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).
What is the difference between a toxic substance and harmful one?
A toxic substance is harmful at low doses, typically due to its inherent chemical properties. A harmful substance, on the other hand, may cause harm through other means such as misuse or overexposure. In general, all toxic substances are harmful, but not all harmful substances are necessarily toxic.
