Across
  1. 1. the measurement or extent of something from end to end.
  2. 5. Formed by losing and gaining of electrons between metal and nonmetal
  3. 7. Positively charged subatomic particle of an atom
  4. 10. the quality or state of being correct or precise.
  5. 11. a substance or object that is solid rather than liquid or fluid
  6. 13. Phase change in which liquid is converted to solid
  7. 14. Called as solution a mixture with uniform composition.
  8. 16. The quantity of matter in the body
  9. 17. states that atoms other than hydrogen tend to form bonds until surrounded by eight valence electrons
  10. 18. Anything that has mass and occupies space
  11. 21. Uncharged particle found within the atomic nuclei
  12. 24. the branch of chemistry concerned with the application of the techniques and theories of physics to the study of chemical systems.
  13. 26. Element that appears at the far right side of the periodic table
  14. 27. Composed of two or more substances combined physically in variable proportions
  15. 32. The separation of elemental metals from the mixtures
  16. 35. 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.
  17. 36. the branch of science that deals with the identification of the substances of which matter is composed.
  18. 37. The sum of the number of protons and neutrons in its nucleus
  19. 40. Horizontal row in the periodic table
  20. 41. a period of time equal to sixty seconds or a sixtieth of an hour.
  21. 44. 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.
  22. 46. Phase change that involves the conversion from solid to liquid
  23. 47. Process in which the solid particles are filtered to allow the liquid or filtrate to pass through the filter and be collected as residue
  24. 48. 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
  25. 49. Elements at the left side and in the center of the periodic table
  26. 50. it is a branch of chemistry that studies and uses instruments and methods used to separate identify and quantify matter.
  27. 51. the size length or amount of something as established by measuring.
Down
  1. 2. Mixture whose a composition varies from position to position within a sample.
  2. 3. a substance that flows freely but is of constant volume having a consistency like that of water or oil.
  3. 4. The amount of space occupied by a substance
  4. 6. Ratio of the mass of an object to the volume occupied by that object.
  5. 8. a result without the expected content
  6. 9. Compound that consists of two charged ions
  7. 12. phase change in which liquid is converted to gas
  8. 15. insert gas located at the rightmost side of the periodic table

  15. 28. Specific energy value of electrons for an atom
  16. 29. the quality, condition, or fact of being exact and accurate.
  17. 30. 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.
  18. 31. inner transition elements located in the first row of the f block in the periodic table
  19. 33. Formed when atom loses or gains electron
  20. 34. it is a branch of chemistry that deals with synthesis and behavior of inorganic and organometallic compounds.
  21. 38. The digits in any measurement that are known with certainty plus one digit which is uncertain
  22. 39. Organic compound with carbon and oxygen only
  23. 42. a metric unit of length equal to one hundredth of a meter.
  24. 43. Indicates that one mole of an element has a mass in grams numerically equal to its atomic mass units
  25. 45. Separates components of mixture at different boiling points.
