Across
  1. 1. it is a branch of chemistry that studies and uses instruments and methods used to separate identify and quantify matter.
  2. 7. states that atoms other than hydrogen tend to form bonds until surrounded by eight valence electrons
  3. 8. movement of one fluid through another.
  4. 15. The digits in any measurement that are known with certainty plus one digit which is uncertain
  5. 16. 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.
  6. 19. Elements at the left side and in the center of the periodic table
  7. 21. bond Formed by losing and gaining of electrons between metal and nonmetal
  8. 22. Negatively charged subatomic particle of an atom
  9. 23. Positively charged subatomic particle of an atom
  10. 25. 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. 28. Uncharged particle found within the atomic nuclei
  12. 30. a substance or object that is solid rather than liquid or fluid
  13. 37. the quality or state of being correct or precise.
  14. 39. Mixture whose a composition varies from position to position within a sample.
  15. 41. The quantity of matter in the body
  16. 42. Indicates that one mole of an element has a mass in grams numerically equal to its atomic mass units
  17. 45. inner transition elements located in the first row of the f block in the periodic table
  18. 47. the quality, condition, or fact of being exact and accurate.
  19. 48. a substance that flows freely but is of constant volume having a consistency like that of water or oil.
  20. 49. a metric unit of length equal to one hundredth of a meter.
  21. 51. Called as solution a mixture with uniform composition.
Down
  1. 2. Element that appears at the far right side of the periodic table
  2. 3. The sum of the number of protons and neutrons in its nucleus
  3. 4. 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.
  4. 5. Elements found in the zigzag order in the periodic table
  5. 6. 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.
  6. 9. Horizontal row in the periodic table
  7. 10. Process in which the solid particles are filtered to allow the liquid or filtrate to pass through the filter and be collected as residue
  8. 11. phase change in which liquid is converted to gas
  9. 12. The separation of elemental metals from the mixtures
  10. 13. 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
  11. 14. Organic compound with carbon and oxygen only
  12. 17. the size length or amount of something as established by measuring.
  13. 18. it is a branch of chemistry that deals with synthesis and behavior of inorganic and organometallic compounds.
  14. 20. the measurement or extent of something from end to end.
  15. 24. the branch of chemistry concerned with the application of the techniques and theories of physics to the study of chemical systems.
  16. 26. Compound that consists of two charged ions
  17. 27. Ratio of the mass of an object to the volume occupied by that object.
