Across
  1. 1. Composed of two or more substances combined physically in variable proportions
  2. 2. a metric unit of length equal to one hundredth of a meter.
  3. 5. Organic compound with carbon and oxygen only
  4. 7. Elements at the left side and in the center of the periodic table
  5. 8. 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.
  6. 10. the size length or amount of something as established by measuring.
  7. 12. Positively charged subatomic particle of an atom
  8. 14. a substance that flows freely but is of constant volume having a consistency like that of water or oil.
  9. 15. Indicates that one mole of an element has a mass in grams numerically equal to its atomic mass units
  10. 17. 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.
  11. 18. 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.
  12. 27. the fundamental unit of length in the metric system equal to 100 centimeters or approximately 39.37 inches.
  13. 28. Group 7A elements
  14. 29. Process in which the solid particles are filtered to allow the liquid or filtrate to pass through the filter and be collected as residue
  15. 30. a substance or object that is solid rather than liquid or fluid
  16. 33. Horizontal row in the periodic table
  17. 35. Negatively charged subatomic particle of an atom
  18. 37. Element that appears at the far right side of the periodic table
  19. 38. it is a branch of chemistry that deals with synthesis and behavior of inorganic and organometallic compounds.
  20. 39. The digits in any measurement that are known with certainty plus one digit which is uncertain
  21. 40. The amount of space occupied by a substance
  22. 44. Separates components of mixture at different boiling points.
  23. 45. phase change in which liquid is converted to gas
  24. 46. a period of time equal to sixty seconds or a sixtieth of an hour.
  25. 48. Specific energy value of electrons for an atom
  26. 49. inner transition elements located in the first row of the f block in the periodic table
Down
  1. 1. The separation of elemental metals from the mixtures
  2. 3. The quantity of matter in the body
  3. 4. Uncharged particle found within the atomic nuclei
  4. 6. the quality or state of being correct or precise.
  5. 9. a metric unit of capacity formerly defined as the volume of one kilogram of water under standard conditions now equal to 1 000 cubic centimeters
  6. 11. Elements found in the zigzag order in the periodic table
  7. 12. the branch of chemistry concerned with the application of the techniques and theories of physics to the study of chemical systems.
  8. 13. it is a branch of chemistry that studies and uses instruments and methods used to separate identify and quantify matter.

  16. 25. states that atoms other than hydrogen tend to form bonds until surrounded by eight valence electrons
  17. 26. Called as solution a mixture with uniform composition.
  18. 31. Phase change in which liquid is converted to solid
  19. 32. Anything that has mass and occupies space
  20. 34. Compound that consists of two charged ions
