  9. 16. Called as solution a mixture with uniform composition.
  10. 21. Elements found in the zigzag order in the periodic table
  11. 22. The sum of the number of protons and neutrons in its nucleus

  13. 26. Composed of two or more substances combined physically in variable proportions
  14. 28. Specific energy value of electrons for an atom
  15. 31. Process in which the solid particles are filtered to allow the liquid or filtrate to pass through the filter and be collected as residue
  16. 33. Ratio of the mass of an object to the volume occupied by that object.
