Across
  1. 4. Formed when atom loses or gains electron
  2. 5. Phase change in which liquid is converted to solid
  3. 6. gas: insert gas located at the rightmost side of the periodic table
  4. 8. Ratio of the mass of an object to the volume occupied by that object.
  5. 9. compound: Compound that consists of two charged ions
  6. 10. chemistry: it is a branch of chemistry that studies and uses instruments and methods used to separate: identify: and quantify matter.
  7. 11. bond: Formed by losing and gaining of electrons between metal and nonmetal
  8. 12. Anything that has mass and occupies space
  9. 14. a substance that flows freely but is of constant volume: having a consistency like that of water or oil.
  10. 17. separation: The separation of elemental metals from the mixtures
  11. 18. figures: The digits in any measurement that are known with certainty plus one digit which is uncertain
  12. 20. The amount of space occupied by a substance
  13. 21. the measurement or extent of something from end to end
  14. 22. The quantity of matter in the body
  15. 23. Negatively:charged subatomic particle of an atom
  16. 25. number: The sum of the number of protons and neutrons in its nucleus
  17. 28. a period of time equal to sixty seconds or a sixtieth of an hour.
  18. 29. Phase change that involves the conversion from solid to liquid
  19. 30. chemistry: 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.
  20. 31. Separates components of mixture at different boiling points.
  21. 35. Positively:charged subatomic particle of an atom
  22. 36. mixture: Mixture whose a composition varies from position to position within a sample.
  23. 37. level: Specific energy value of electrons for an atom
  24. 40. 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.
  25. 41. Group 7A elements
  26. 43. movement of one fluid through another.
  27. 45. inner transition elements located in the first row of the f:block in the periodic table
  28. 47. Organic compound with carbon and oxygen only
  29. 48. Substance consisting of only one kind of atom
Down
  1. 1. the fundamental unit of length in the metric system: equal to 100 centimeters or approximately 39.37 inches.
  2. 2. Element that appears at the far right side of the periodic table
  3. 3. mixture: Called as solution: a mixture with uniform composition.
  4. 7. Process in which the solid particles are filtered to allow the liquid or filtrate to pass through the filter: and be collected as residue
  5. 13. Composed of two or more substances: combined physically in variable proportions
  6. 15. physical property: physical property that does not depend on the size or amount of the sample
  7. 16. 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.
  8. 19. phase change in which liquid is converted to gas

  11. 26. Uncharged particle found within the atomic nuclei
  12. 27. Horizontal row in the periodic table
  13. 28. the size: length: or amount of something: as established by measuring.
  14. 32. rule: states that atoms other than hydrogen tend to form bonds until surrounded by eight valence electrons
  15. 33. Elements found in the zigzag order in the periodic table
  16. 34. a substance or object that is solid rather than liquid or fluid
  17. 38. chemistry: the branch of chemistry concerned with the application of the techniques and theories of physics to the study of chemical systems.
  18. 39. a metric unit of length: equal to one hundredth of a meter.
  19. 42. mass: Indicates that one mole of an element has a mass in grams numerically equal to its atomic mass units
  20. 44. 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.
  21. 46. Chemistry: it is a branch of chemistry that deals with synthesis and behavior of inorganic and organometallic compounds.
