Across
  1. 2. number: The sum of the number of protons and neutrons in its nucleus
  2. 4. bond: Formed by losing and gaining of electrons between metal and nonmetal
  3. 6. Uncharged particle found within the atomic nuclei
  4. 7. figures: The digits in any measurement that are known with certainty plus one digit which is uncertain
  5. 9. 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 quantity of matter in the body
  7. 12. Formed when atom loses or gains electron
  8. 15. chemistry: the branch of chemistry concerned with the application of the techniques and theories of physics to the study of chemical systems.
  9. 17. mixture: Called as solution: a mixture with uniform composition.
  10. 19. a period of time equal to sixty seconds or a sixtieth of an hour.
  11. 20. level: Specific energy value of electrons for an atom
  12. 22. Horizontal row in the periodic table
  13. 27. mixture: Mixture whose a composition varies from position to position within a sample.
  14. 30. the quality, condition, or fact of being exact and accurate.

  19. 42. the closeness of a single measurement to its true value.
  20. 43. physical property: physical property that does not depend on the size or amount of the sample
  21. 44. phase change in which liquid is converted to gas
  22. 45. 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.
  23. 47. The amount of space occupied by a substance
  24. 48. Elements found in the zigzag order in the periodic table
  25. 50. Phase change in which liquid is converted to solid

Down
  1. 1. a substance that flows freely but is of constant volume: having a consistency like that of water or oil.
  2. 2. Anything that has mass and occupies space
  3. 3. a substance or object that is solid rather than liquid or fluid
  4. 5. inner transition elements located in the first row of the f:block in the periodic table
