Which feature of nuclear fission reactions allows these reactions to take place in a chain reaction?

Thermal energy is released and heats up the reactants.

More smaller atoms form that can undergo fission.

A larger atom is formed, which can then be split.

Neutrons start the reaction and are released during it.

Respuesta :

Answer:

Neutrons start the reaction and are released during it

Explanation:

N

Neutrons start the reaction and are released during it is the correct answer.

What is responsible for chain reaction?

Neutrons start the reaction and are released during it is the feature of nuclear fission reactions that allows these reactions to take place in a chain reaction because the neutron that is released hit the other atom which leads to the start of other reaction and so on.

so we can conclude that Neutrons start the reaction and are released during it is the correct answer.
