Select the statement that is trueGroup of answer choicesThe hydrogen-1 nucleus is simply a neutronHydrogen burning releases energy into the surroundings as heatAll atoms are generated from the simplest nuclide, heliumNew element-forming reactions are endothermic until iron.

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

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
