General Chemistry

Across

1. Composed of two or more substances combined physically in variable proportions
2. a metric unit of length equal to one hundredth of a meter.
5. Organic compound with carbon and oxygen only
7. Elements at the left side and in the center of the periodic table
8. 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.
10. the size length or amount of something as established by measuring.
12. Positively charged subatomic particle of an atom
14. a substance that flows freely but is of constant volume having a consistency like that of water or oil.
15. Indicates that one mole of an element has a mass in grams numerically equal to its atomic mass units
17. 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.
18. the branch of science that deals with the identification of the substances of which matter is composed.
27. the fundamental unit of length in the metric system equal to 100 centimeters or approximately 39.37 inches.
28. Group 7A elements
29. Process in which the solid particles are filtered to allow the liquid or filtrate to pass through the filter and be collected as residue
30. a substance or object that is solid rather than liquid or fluid
33. Horizontal row in the periodic table
35. Negatively charged subatomic particle of an atom
37. Element that appears at the far right side of the periodic table
38. it is a branch of chemistry that deals with synthesis and behavior of inorganic and organometallic compounds.
39. The digits in any measurement that are known with certainty plus one digit which is uncertain
40. The amount of space occupied by a substance
44. Separates components of mixture at different boiling points.
45. phase change in which liquid is converted to gas
46. a period of time equal to sixty seconds or a sixtieth of an hour.
48. Specific energy value of electrons for an atom
49. inner transition elements located in the first row of the f block in the periodic table

Down

1. The separation of elemental metals from the mixtures
3. The quantity of matter in the body
4. Uncharged particle found within the atomic nuclei
6. the quality or state of being correct or precise.
9. 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
11. Elements found in the zigzag order in the periodic table
12. the branch of chemistry concerned with the application of the techniques and theories of physics to the study of chemical systems.
13. it is a branch of chemistry that studies and uses instruments and methods used to separate identify and quantify matter.
16. 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.
19. Substance consisting of only one kind of atom
20. the measurement or extent of something from end to end.
21. Ratio of the mass of an object to the volume occupied by that object.
22. The sum of the number of protons and neutrons in its nucleus
23. Mixture whose a composition varies from position to position within a sample.
24. movement of one fluid through another.
25. states that atoms other than hydrogen tend to form bonds until surrounded by eight valence electrons
26. Called as solution a mixture with uniform composition.
31. Phase change in which liquid is converted to solid
32. Anything that has mass and occupies space
34. Compound that consists of two charged ions
36. Phase change that involves the conversion from solid to liquid
41. Formed when atom loses or gains electron
42. insert gas located at the rightmost side of the periodic table
43. the quality, condition, or fact of being exact and accurate.
47. bond Formed by losing and gaining of electrons between metal and nonmetal
