Nuclear fission and nuclear fusion are both processes by which the atoms of matter are altered to create energy, but they are opposite processes. In fission, one atom splits into two, whereas fusion combines two lighter atoms into a larger one. Although both processes release energy, fission is the more controllable reaction. It is used in nuclear power plants to produce electricity, usually with Uranium-235. Fusion, on the other hand, is the process that powers the sun. Fusion releases an enormous amount of energy, several times that of fission. Fusion is used not for power plants but for thermonuclear weapons.Which organisational structure does this text primarily use?

In 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.

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.
