Across
  1. 6. mixture: Mixture whose a composition varies from position to position within a sample.
  2. 10. chemistry: the branch of chemistry concerned with the application of the techniques and theories of physics to the study of chemical systems.
  3. 11. Substance consisting of only one kind of atom
  4. 12. Phase change in which liquid is converted to solid
  5. 13. 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. 15. Elements found in the zigzag order in the periodic table
  7. 23. chemistry: it is a branch of chemistry that studies and uses instruments and methods used to separate: identify: and quantify matter.
  8. 24. a metric unit of length: equal to one hundredth of a meter.
  9. 28. the measurement or extent of something from end to end.
  10. 30. Separates components of mixture at different boiling points.
  11. 31. physical property: physical property that does not depend on the size or amount of the sample
  12. 35. movement of one fluid through another.
  13. 36. Horizontal row in the periodic table
  14. 38. mass: Indicates that one mole of an element has a mass in grams numerically equal to its atomic mass units
  15. 39. 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.
  16. 41. Ratio of the mass of an object to the volume occupied by that object.
  17. 43. inner transition elements located in the first row of the f:block in the periodic table
  18. 46. gas: insert gas located at the rightmost side of the periodic table
  19. 47. bond: Formed by losing and gaining of electrons between metal and nonmetal
  20. 48. Organic compound with carbon and oxygen only
  21. 49. 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.
Down
  1. 1. Positively:charged subatomic particle of an atom
  2. 2. Element that appears at the far right side of the periodic table
  3. 3. the fundamental unit of length in the metric system: equal to 100 centimeters or approximately 39.37 inches.
  4. 4. a substance that flows freely but is of constant volume: having a consistency like that of water or oil.
  5. 5. 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. 6. mixture: Called as solution: a mixture with uniform composition.
  7. 7. a period of time equal to sixty seconds or a sixtieth of an hour.
  8. 8. 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
  9. 9. Uncharged particle found within the atomic nuclei
  10. 14. compound: Compound that consists of two charged ions
  11. 16. Negatively:charged subatomic particle of an atom
  12. 17. the closeness of a single measurement to its true value.
  13. 18. figures: The digits in any measurement that are known with certainty plus one digit which is uncertain
  14. 19. Anything that has mass and occupies space
  15. 20. Phase change that involves the conversion from solid to liquid
  16. 21. Elements at the left side and in the center of the periodic table
  17. 22. the size: length: or amount of something: as established by measuring.
  18. 25. separation: The separation of elemental metals from the mixtures
  19. 26. rule: states that atoms other than hydrogen tend to form bonds until surrounded by eight valence electrons
  20. 27. Chemistry: it is a branch of chemistry that deals with synthesis and behavior of inorganic and organometallic compounds.
