14. choose the best answer. the periodic tables largest group, ____, includes radioactive elements. alkali metals nonmetals the lanthanide series transition metals 15. choose the best answer. increasing the ____ makes it easier for dissolution to occur. reactive ratio surface area of a solute amount of solute number of substances

Answer

Brief Explanations:

  1. The transition - metals group is the largest group in the periodic table and includes radioactive elements such as technetium. Alkali metals, non - metals, and the lanthanide series are not the largest groups.
  2. Increasing the surface area of a solute exposes more of the solute to the solvent, making dissolution easier. The reactive ratio is not a factor in simple dissolution, increasing the amount of solute doesn't make dissolution easier per - se, and the number of substances is not directly related to the ease of dissolution of a particular solute.

Answer:

  1. D. transition metals
  2. B. surface area of a solute
