Hedea made a study chart about nuclear energy. A 3-column table with 2 rows titled Nuclear Energy. The first column labeled Reaction has entries fission, fusion. The second column labeled Change to Nucleus has entries nuclei of atoms are split, nuclei of atoms are joined. The third column has entries Energy Conversion has entries converts nuclear to thermal, converts nuclear to radiant. Which best describes the error in Hedea’s chart? The nuclei of atoms are split apart in both fission and fusion. The nuclei of atoms are joined together in both fission and fusion. Fission converts nuclear energy to electrical energy, not thermal energy. Fission and fusion convert nuclear energy to both radiant and thermal energy.

The image compares the arrangement of electrons in two different neutral atoms. a figure labeled atom q has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has six black spheres. to the left of this figure is another figure labeled atom p. atom p has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has seven black spheres. which of the following best explains the position of the two atoms in the periodic table? atom p has an estimated zeff of 7 and is therefore to the left of atom q, which has a zeff of 6. atom p has an estimated zeff of 7 and is therefore to the right of atom q, which has a zeff of 6. atom p has an estimated zeff of 5 and is therefore below atom q, which has a zeff of 4. atom p has an estimated zeff of 5 and is therefore above atom q, which has a zeff of 4.
