Question

In fission, a ________ _________ is one where a neutron imbeds itself in the nucleus of a U-235 atom causing it to break apart. After destructing, more neutrons are created. These neutrons can carry on the cycle by finding more U-235, and, again, starting the fissioning process.
a. chain reaction

b. ground zero

Answer 1

a. chain reaction

Explanation:

In a fission, a chain reaction is one where a neutron embeds itself in the nucleus of an U-235 atom and causes it to break apart. After this, more neutrons are created. The neutrons carry on the cycle by starting the fission process over and over again.

Chain reactions typifies most nuclear reactions taking place in the nucleus of an atom.

They are repeated loops that takes place until an atom reaches it state of stability.

• They are not exclusive to fission reactions alone.
• Chain reactions also takes place during nuclear fusion
• In fusion two atoms combines to produce a single nuclide.
• The steps goes on and on
• This why the sun keeps burning and bursting with energy
