What is the best definition of nuclear fission?

: a process in which the nucleus of a heavy atom is split apart.

What is fission in short?

Fission occurs when a neutron slams into a larger atom, forcing it to excite and spilt into two smaller atoms—also known as fission products. Additional neutrons are also released that can initiate a chain reaction. When each atom splits, a tremendous amount of energy is released.

What is nuclear fission and example?

Fission is the splitting of an atomic nucleus into two or more lighter nuclei accompanied by energy release. For example, the fission of one kilogram of uranium releases as much energy as burning around four billion kilograms of coal.

What is nuclear fission Class 10?

The process in which the heavy nucleus of a radioactive atom (such as uranium, plutonium or thorium) splits up into smaller nuclei when bombarded with low energy neutrons, is called nuclear fission.

What is the best definition of nuclear fission quizlet?

nuclear fission. a nuclear reaction in which a massive nucleus splits into smaller nuclei with the simultaneous release of energy.

What is nuclear fission Class 12?

The process of splitting of a heavy nucleus into two nuclei of comparable size and release of large energy is called fission.

What is example of fission?

In fission, energy is gained by splitting apart heavy atoms, for example uranium, into smaller atoms such as iodine, caesium, strontium, xenon and barium, to name just a few. However, fusion is combining light atoms, for example two hydrogen isotopes, deuterium and tritium, to form the heavier helium.

What is nuclear fission and fusion?

Both fission and fusion are nuclear reactions that produce energy, but the processes are very different. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.

What is nuclear fission quizlet?

Nuclear fission is splitting of a nucleas into two approximately equal fragments and the release of two or three neutrons. It normally occurs when a neutron hits a uranium 235 nucleus or plutonium 239 nucleus. Fission neutrons.

What is nuclear fission answers com?

Nuclear fission is a reaction wherein a heavy nucleus is bombarded by neutrons and thus becomes unstable, which causes it to decompose into two nuclei with equivalent size and magnitude, with a great detachment of energy and the emission of two or three neutrons.

What is meaning of fission and fusion?

Both fission and fusion are nuclear processes by which atoms are altered to create energy, but what is the difference between the two? Simply put, fission is the division of one atom into two, and fusion is the combination of two lighter atoms into a larger one.

What is the process of nuclear fission?

Nuclear fission is a process by which the nucleus of an atom is split into two or more smaller nuclei, known as fission products. The fission process also releases extra neutrons, which can then split additional atoms, resulting in a chain reaction that releases a lot of energy.
