What else can I help you with?
Do fission products have smaller nuclei than reactants?
Yes, fission products typically have smaller nuclei than the reactants. During fission, a heavy nucleus splits into two or more smaller nuclei, releasing energy and neutrons. These fission products are generally lighter and more stable than the original nucleus.
What are the products and reactants in the primary fusion reaction carried out within the sun?
The reactants are Hydrogen atoms and products are Helium atoms. Because Helium atoms are larger than Hydrogen atom, large amount of energy is released from the net binding energy that resulted during the fusion process.
Identify the end products of the nuclear fusion process that occurs in the sun?
The end products of nuclear fusion in the sun are helium nuclei (alpha particles) and energy in the form of gamma rays and neutrinos. Four hydrogen nuclei combine to form one helium nucleus through a series of fusion reactions.
What is the required for half a sample of radioactive nuclei to decay called?
not sure you're asking exactly but I think the answer your looking for is radioactive half-life
The nuclei of hydrogen has a positive charge How does this affect the chances of nuclear fusion occurring?
The positive charges of hydrogen nuclei cause repulsion, it is very difficult to bring two hydrogen nuclei close enough for them to fuse into helium. However, if they can be forced to fuse, a huge amount of energy is released.
What are isotopes which send off charged particles and radiant energy from their nuclei called?
It is called a radioisotope.
Is atomic nuclei required in a chemical reaction?
No, atomic nuclei is not required for a chemical reaction.
What is the half lie of a radioisotope?
The half-life of a radioisotope is the time it takes for half of the radioactive nuclei in a sample to decay. It is a characteristic property of each radioisotope and determines the rate at which the isotopes decay.
What Products of mitosis are?
The products of mitosis are two genetically identical nuclei
Do fission products have smaller nuclei than reactants?
Yes, fission products typically have smaller nuclei than the reactants. During fission, a heavy nucleus splits into two or more smaller nuclei, releasing energy and neutrons. These fission products are generally lighter and more stable than the original nucleus.
What nuclei and energy are the products of the nuclear fusion of the suns hydrogen?
Helium
What is an an atom with variable nuclei called?
If the nucleus is changing due to natural causes this would be due to being radioactive and emitting alpha or beta particles. If it is caused by irradiation in a neutron flux it would be called a radioisotope.
Why is a large amount kinetic energy required to force nuclei together?
A large amount of kinetic energy is required to force nuclei together because nuclei are positively charged and repel each other due to electromagnetic forces. Overcoming this repulsion requires a significant amount of energy to bring the nuclei close enough for the strong nuclear force to take effect and bind them together in a nuclear reaction.
What is major problem related to causing nuclei to fuse into a single nucleus?
The incredible temperatures required.
How do the products of a fusion differ from the products of a fission reaction?
One thing that makes fusion products different from fission products obviously is the fact that fusion products are heavier than the original two nuclei and fission products are lighter than the original nucleus
Why is it called Nuclear Fission?
It is called nuclear fission as in this process the heavy nuclei are split into fragments (or fission products).
What is the half life of radioisotope?
Half life is the time taken for approximately half of the available nuclei in a sample of radioactive material to decay into something else. It's a characteristic of the isotope, for example, the half life of the isotope of iodine, I131 is 8.08 days. Half lives can vary from fractions of a second to thousands of years.
