Across
  1. 3. Indicates that one mole of an element has a mass in grams numerically equal to its atomic mass units
  2. 5. Ratio of the mass of an object to the volume occupied by that object.
  3. 8. states that atoms other than hydrogen tend to form bonds until surrounded by eight valence electrons
  4. 9. Elements at the left side and in the center of the periodic table
  5. 10. it is a branch of chemistry that deals with synthesis and behavior of inorganic and organometallic compounds.
  6. 11. 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.
  7. 12. the measurement or extent of something from end to end.
  8. 13. Positively charged subatomic particle of an atom
  9. 16. insert gas located at the rightmost side of the periodic table
  10. 17. bond Formed by losing and gaining of electrons between metal and nonmetal
  11. 21. The sum of the number of protons and neutrons in its nucleus
  12. 23. movement of one fluid through another.
  13. 25. Group 7A elements
  14. 26. Substance consisting of only one kind of atom
  15. 28. Separates components of mixture at different boiling points.
  16. 29. 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
  17. 31. Specific energy value of electrons for an atom
  18. 33. Called as solution a mixture with uniform composition.
  19. 34. The quantity of matter in the body
  20. 36. The amount of space occupied by a substance
  21. 37. it is a branch of chemistry that studies and uses instruments and methods used to separate identify and quantify matter.
  22. 39. a substance or object that is solid rather than liquid or fluid
  23. 40. Element that appears at the far right side of the periodic table
  24. 41. Process in which the solid particles are filtered to allow the liquid or filtrate to pass through the filter and be collected as residue
  25. 43. Horizontal row in the periodic table
  26. 44. Mixture whose a composition varies from position to position within a sample.
  27. 45. the quality, condition, or fact of being exact and accurate.
  28. 47. the size length or amount of something as established by measuring.
  29. 48. Compound that consists of two charged ions
Down
  1. 1. inner transition elements located in the first row of the f block in the periodic table
  2. 2. the branch of chemistry concerned with the application of the techniques and theories of physics to the study of chemical systems.
  3. 4. Negatively charged subatomic particle of an atom
  4. 6. phase change in which liquid is converted to gas
  5. 7. The separation of elemental metals from the mixtures
  6. 9. the fundamental unit of length in the metric system equal to 100 centimeters or approximately 39.37 inches.
  7. 14. The digits in any measurement that are known with certainty plus one digit which is uncertain
  8. 15. Phase change that involves the conversion from solid to liquid

  16. 32. Elements found in the zigzag order in the periodic table
  17. 33. Organic compound with carbon and oxygen only
  18. 35. Phase change in which liquid is converted to solid
  19. 38. 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.
  20. 42. Uncharged particle found within the atomic nuclei
  21. 46. Formed when atom loses or gains electron
