Both a fusion reaction and a fission reaction do what?

Answer 1

Both fusion and fission have the same procedures in common, but there are different requirement to initiate the reaction. What happens is that in a fission reaction, atomic bombs undergoes fission reaction. A highly reactive and or in-fact radioactive element such as uranium, specially Uranium-135. To initiate the reaction, a free proton is released which is then absorbed by the uranium element, which destabilises its arrangement so it emits radioactive particles such as alpha and beta, splitting the molecule into two pieces and more three free neutrons and that neutrons gets absorbed by another nucleus and there goes the chain reaction and huge and huge amount of energy is released.

With fusion reaction, its all about how the sun works, actually works and we don't have the technology to be able use it. To initiate the reaction it requires about 10^8 degrees, which is boom boom temperature. Fusion reaction occurs when two smaller nuclei joins in one piece and huge amount nuclear energy is released.

Answer 2

Nuclear fusion is the process where two or more atomic nuclei join together to create one nucleus.

Example: the sun

Nuclear fission is the process where the nucleus of an atom splits into smaller nuclei.

Example: atomic bombs

Answer 3

Nuclear fusion and fission are the opposites of each other, but both involve changing the internal structure of atoms.

Fission is where the nucleus of an atom is split. This can be done by firing a neutron (a sub-atomic particle which has no electrical charge; i.e. it is electrically neutral, hence the name) at the nucleus of an atom and is the principle upon which nuclear weapons work. A neutron is fired (because it has no charge it can easily penetrate the charged nucleus) first through a "moderator" which slows it down in order to increase the chance that it will "be caught" by the nucleus of an atom of a substance such as uranium. As the neutron splits the nucleus of the atom more neutrons are released from the affected atom which in turn split other surrounding atoms. This is called a chain reaction and it is this that causes an explosion to occur.

The fission reaction releases a large amount of energy; vastly more than ordinary radioactivity. A substance such as 'Uranium 235' is used as it is inherently unstable and therefore more likely to undergo nuclear fission. A heavy element such as uranium is converted in to two lighter elements by this process. Of course, fission can also be used for more peaceful purposes such as in a nuclear power station where the controlled energy released is used to turn water in to steam which powers a turbine and electrical generator.

Fusion is the opposite. This is where nuclei are joined together (fused) to create a heavier element. The most obvious example is in our Sun where hydrogen nuclei (the lightest, most common (by far) and simplest element in the Universe) are fused together to create helium. The intense heat and pressure inside a star is sufficient to fuse the lighter elements together. This process also releases vast amounts of energy in the form of heat and light. All the naturally occurring elements in the Universe (barring hydrogen and some (not all) helium were created by nuclear fusion either in stars during their lifetime or when stars die and explode (a supernova).

Answer 4

Their products have less mass than their reactants

Answer 5

it causes chain reactions
