Across
  1. 5. Anything that has mass and occupies space
  2. 7. Organic compound with carbon and oxygen only
  3. 9. Separates components of mixture at different boiling points.
  4. 17. Element that appears at the far right side of the periodic table
  5. 20. Compound that consists of two charged ions
  6. 21. Substance consisting of only one kind of atom
  7. 24. Elements at the left side and in the center of the periodic table
  8. 25. a metric unit of length equal to one hundredth of a meter.
  9. 29. the fundamental unit of length in the metric system equal to 100 centimeters or approximately 39.37 inches.
  10. 32. it is a branch of chemistry that studies the structure properties and reactions of organic compounds which contain carbon in covalent bonding. Study of structure determines their chemical composition and formula.
  11. 34. Formed when atom loses or gains electron
  12. 35. Horizontal row in the periodic table
  13. 36. a substance or object that is solid rather than liquid or fluid
  14. 37. the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact combine and change; and the use of these processes to form new substances.
  15. 39. Uncharged particle found within the atomic nuclei
  16. 41. a substance or matter in a state in which it will expand freely to fill the whole of a container having no fixed shape and no fixed volume.
  17. 42. the size length or amount of something as established by measuring.
  18. 43. insert gas located at the rightmost side of the periodic table
  19. 44. the quality, condition, or fact of being exact and accurate.
  20. 47. the branch of chemistry concerned with the application of the techniques and theories of physics to the study of chemical systems.
  21. 49. Indicates that one mole of an element has a mass in grams numerically equal to its atomic mass units
  22. 50. physical property that does not depend on the size or amount of the sample
  23. 51. Phase change in which liquid is converted to solid
Down
  1. 1. Elements found in the zigzag order in the periodic table
  2. 2. a substance that flows freely but is of constant volume having a consistency like that of water or oil.
  3. 3. it is a branch of chemistry that studies and uses instruments and methods used to separate identify and quantify matter.
  4. 4. The quantity of matter in the body
  5. 6. Process in which the solid particles are filtered to allow the liquid or filtrate to pass through the filter and be collected as residue
  6. 8. movement of one fluid through another.
  7. 10. the measurement or extent of something from end to end.

  10. 13. Called as solution a mixture with uniform composition.
  11. 14. it is a branch of chemistry that studies the chemical processes within and relating to living organisms. Biochemical processes give rise to the complexity of life.
  12. 15. a period of time equal to sixty seconds or a sixtieth of an hour.
  13. 16. Positively charged subatomic particle of an atom
