Each time a U235 atom decays, it emits 2-3 neutrons. The likelihood that one of these neutrons is captured by another U235 atom INCREASES with more mass.
The SHAPE of this mass will also play a role, imagine a thin wire of U235, compared to a sphere, with regards to how likely a chain reaction will occur.
Neutron reflection can also help redirect an errant neutron back into the mass so it can react instead.
Compression (increase of density) plays a role as well.

Neutrons released in a fission reaction can strike other nuclei and cause?
further fission reactions, leading to a chain reaction. This process releases more neutrons, producing a large amount of energy. Controlling the rate of the chain reaction is crucial for nuclear power generation and atomic weapons.
When many atoms are split in a chain reaction, a large explosion occurs This is an example of what type of energy conversion?
Your question has 2 parts:Assuming that 1 neutron starts the chain reaction, each generation takes 10ns, each fission produces 2.5 neutrons on average, and the chain reaction lasts 1us; the total fissions = 100000Nuclear energy to kinetic energy to heat energy.
What goes on when a nuclear chain reaction occurs?
A nuclear chain reaction occurs when a nucleus undergoes fission, releasing energy and more neutrons. These neutrons can then collide with other nuclei, causing them to also undergo fission and release additional neutrons. This process continues in a chain reaction, leading to the release of large amounts of energy.
What chemical reaction formed these large molecules what reaction would be needed to break these molecules?
Large molecules are formed through a variety of chemical reactions, such as polymerization or condensation reactions. To break these molecules down, typically a hydrolysis reaction is needed, where water is used to break the bonds holding the large molecules together.

What term describes the reaction process in a fission reaction?
another name for nuclear fission is: E=MC squared
What is a large chain of islands?
An archipelago is a large chain of islands.
Is an enzyme used up by the reaction it catalyze?
Enzymes are highly efficient catalysts, and only small quantities are needed to catalyze the reaction of relatively large amounts of materials.
What is the method that creates a large sample of DNA for testing from a small sample of DNA?
That would probably be polymerase chain reaction or PCR for short.
Why are radioactive substances useful in fission bombs?
Radioactive substances, such as uranium or plutonium, are used in fission bombs because they can undergo nuclear fission, releasing a large amount of energy in a chain reaction. This energy release is what creates the explosive power of the bomb.
What type of reaction is cracking an example of?
Thermal Decomposition
