A radioactive substance is unstable and produces dangerous kinds of radiation. It is unstable because the strong nuclear force that holds the nucleus of the atom together is not balanced with the electric force that wants to push it apart. Because it's unstable, the atoms will decay into more...
ß-andeof40K and64Cu,pandaof185Bi) and even three kinds of radioactivity (e.g.,a,eand epof110Xe, ß-, ß-nand ß-2nof98Rb,e,epande2pof35Ca), happened with different likelihood. In these cases, they say that such radionuclides can undergo radioactive transformations along differen...
Because fusion requires such extreme conditions, “if something goes wrong, then it stops. No heat lingers after the fact.” With fission, uranium is split apart, so the atoms are radioactive and generate heat, even when the fission ends. Despite its many benefits, however, fusion power is ...
Nuclear fissionis what happens when the nucleus of a large radioactive atom splits into two or more smaller nuclei. When this happens, a lot of energy is released, and this is how nuclear power stations work. Lesson Quiz Course 9.1Kviews ...
We can easily explain this if chemical elements really exist as simple particles (atoms, in other words), which snap together like building blocks. Some substances are radioactive: they naturally split into simpler substances and give off tiny particles or energy in the process. Again, this ...
What happens to quarks not in hadrons? What do quarks have to do with radioactive decay? What does two top quarks and one bottom quark make? What composite particle is comprised of three quarks? Are atoms made of quarks? What are dark quarks?
How do atoms have nuclear decay in nature? Is it due to oxygen or nitrogen? "While both compounds and mixtures are combinations, the main difference is that mixtures can be separated by physical means." - ...
Why Are Certain Elements Radioactive? Imagine that you just accidentally inhaled pollen and are awaiting a sneeze. Now, hold onto that feeling. That is what certain atoms experience all the time—the urge to expel out the excess and regain stability. ...
In the thought experiment, a cat is placed in a sealed box with a vial of poison that will kill the cat if some random event happens, such as on the decay of a radioactive atom. From outside the sealed box, whether the cat is alive or dead is unknowable, so the cat is in a st...
What happens to atoms that are radioactive? What happens to ideas in science? In a chemical reaction, are atoms created or destroyed? What happens to an atom when it absorbs energy? What is the difference between chemical and nuclear reactions? What happens to the mass of matter during expan...
