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

What happens during nuclear fission?Multiple choice question.Nuclei combine to form a large nucleus.A nucleus captures an inner electron.A nucleus decays by emitting alpha or beta radiation.A nucleus splits into smaller nuclei.

The diagram shows a neutron colliding with a nucleus of U-235, splitting the nucleus and producing three more neutrons.What is the name of this process?Group of answer choicesFusionFission Flag question: Question 2Question 21 ptsWhat form of energy is released in this process? Flag question: Question 3Question 31 ptsHow does this process can lead to a chain reaction.Group of answer choicesThe protons collide with another uranium nucleusThe neutrons collide with another uranium nucleusThe electrons collide with another uranium nucleus Flag question: Question 4Question 41 ptsThe diagram shows a nuclear reactor.What is the name of the part labelled A? Flag question: Question 5Question 51 ptsWhat is the liquid labelled B? Flag question: Question 6Question 61 ptsWhat is the effect of moving A out of the reactor?Group of answer choicesthe rate of reaction increasesthe rate of reaction decreasesnothing happens Flag question: Question 7Question 71 ptsWhat role is played by the part labelled B?Group of answer choicesmakes the neutrons move fasterslows the neutrons down

Which statement best describes the process of beta decay?*1 pointAn unstable nucleus releases a particle containing two protons and two neutrons.A destabilized (induced) nucleus splits into two or more nuclei.Two nuclei combine to form one larger nuclei.An unstable nucleus releases an electron.

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.

Which statement describes the process of nuclear fusion?Multiple choice question.Large nuclei split into smaller nuclei.A nucleus emits alpha or beta particles, creating a new nucleus.Electrons from inner energy levels of the atom are captured by the nucleus.Small nuclei join to form a larger nucleus.
