Across
- 1. it is a branch of chemistry that studies and uses instruments and methods used to separate identify and quantify matter.
- 7. states that atoms other than hydrogen tend to form bonds until surrounded by eight valence electrons
- 8. movement of one fluid through another.
- 15. The digits in any measurement that are known with certainty plus one digit which is uncertain
- 16. the branch of science that deals with the identification of the substances of which matter is composed.
- 19. Elements at the left side and in the center of the periodic table
- 21. bond Formed by losing and gaining of electrons between metal and nonmetal
- 22. Negatively charged subatomic particle of an atom
- 23. Positively charged subatomic particle of an atom

- 41. The quantity of matter in the body
- 42. Indicates that one mole of an element has a mass in grams numerically equal to its atomic mass units
- 45. inner transition elements located in the first row of the f block in the periodic table
- 47. the quality, condition, or fact of being exact and accurate.
- 48. a substance that flows freely but is of constant volume having a consistency like that of water or oil.
- 49. a metric unit of length equal to one hundredth of a meter.
- 51. Called as solution a mixture with uniform composition.
Down
- 2. Element that appears at the far right side of the periodic table
- 3. The sum of the number of protons and neutrons in its nucleus
- 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.
- 5. Elements found in the zigzag order in the periodic table
- 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.

- 31. insert gas located at the rightmost side of the periodic table
- 32. Anything that has mass and occupies space
- 33. a chemical substance that neutralizes some elements.
- 34. the fundamental unit of length in the metric system equal to 100 centimeters or approximately 39.37 inches.
