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

- 42. mass: Indicates that one mole of an element has a mass in grams numerically equal to its atomic mass units
- 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.
- 46. Chemistry: it is a branch of chemistry that deals with synthesis and behavior of inorganic and organometallic compounds.
