What process takes place when uranium-235 splits into two smaller nuclei plus neutrons?A.Beta decayB.FusionC.FissionD.Alpha decay

In nuclear reactors, we use Uranium-235 (U-235) as our fuel. To harness its energy, we must fire neutrons at the atoms, which causes them to break apart into smaller particles. When you fire a neutron at U-235 and the U-235 nucleus splits, how many other atoms do you get?247

Because uranium-235 isn't found naturally in large quantities, engineers increase its concentration in nuclear fuel so that a chain reaction is more likely to occur. What is the name of this process?A.FusionB.ProliferationC.EnrichmentD.ContainmentSUBMITarrow_backPREVIOUS

Question 131 ptsWhich occurs in a fusion reaction between two atoms?Group of answer choicesEnergy is absorbed as a less stable element forms.A new element is formed and energy is released.Energy is converted into mass and forms a heavier element.The nuclei of the atoms are split apart and energy is released. Flag question: Question 14Question 141 ptsIn what way are nuclear fission and nuclear fusion similar?Group of answer choicesBoth processes involve the decay of nuclei of atoms.Both processes result in formation of one or more new elements.Both processes are currently used to generate electrical energy.Both processes occur naturally inside the core of a star.

What is nuclear fission?The joining together of two small nucleiThe process which causes the release of energy in the core of the SunThe splitting up of a large and unstable nucleusThe decay of a radioactive nucleus (with the release of an alpha particle, a beta particle, a gamma ray or a neutron)2Which of the following occurs in the reactor of a working nuclear power station which is connected to the National Grid?Nuclear fusionSpontaneous fission onlyBoth spontaneous and induced fissionInduced fission only3The motion of which of the following particles is responsible for nuclear (fission) chain reactions?NeutronsElectronsAlpha particlesProtons4Which of the following elements can be used to stop neutrons within the control rods of a nuclear reactor?BerylliumBoronBariumBismuth5What is nuclear fusion?The joining together of two small nucleiThe process which causes the release of energy in the reactor of a working nuclear power station which is supplying electrical energy to the National GridThe decay of a radioactive nucleus (with the release of an alpha particle, a beta particle, a gamma ray or a neutron)The splitting up of a large and unstable nucleus6Energy is released in both fission and fusion reactions.  Which of the following statements about these types of reactions is correct?Whether the mass of the products is less than, equal to or greater than the mass of the reactants depends on the exact reaction which has taken placeThe mass of the products is equal to the mass of the reactantsThe mass of the products is less than the mass of the reactantsThe mass of the products is greater than the mass of the reactants
