Select the statement that is trueGroup of answer choicesAll atoms are generated from the simplest nuclide, heliumHydrogen burning releases energy into the surroundings as heatNew element-forming reactions are endothermic until iron.The hydrogen-1 nucleus is simply a neutron

Select the statement that is trueGroup of answer choicesAs the star exhausts its hydrogen, it begins lithium burning to fuse heavier nuclei to form increasingly larger atomsA gamma ray has energy, mass and chargeIn star formation, clouds of atomic hydrogen are pulled together by electrostatic attractionsAll atoms are generated from the simplest nuclide, hydrogen, by nuclear reactions

The dominant reaction that occurs in our sun could be described as?Group of answer choicesfour hydrogen atoms combine to form helium and energythree helium atoms fuse to create carbon atoms and energyCarbon atoms and hydrogen atoms fuse to become iron and energyHelium atoms are split to produce hydrogen and energy

The helium flash converts helium nuclei intoGroup of answer choicesboron.iron.carbon.beryllium.oxygen.

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.

The source of the energy emitted by the Sun is the result of reactions involving hydrogen nuclei in the Sun's core.
