Arrange the elements in decreasing order of the number of valence electrons. Rank from most to least number of valence electrons. To rank items as equivalent, overlap them. Part C Number the rows within each block of the periodic table according to the shell for the highest-energy electrons in an atom of those elements. Drag the appropriate labels to their respective targets.
