  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The idea that 1. gaes are made up of particles - 2. gas atoms do not exhibit intermolecular attraactions or repulsions - 3. gas particles are in continuous random motions - 4. collisiosn between two gas particles is not dissipated - and 5. the averag

2. Measures of an attraction that an atom has ffor electrons in a chemical bond

3. Part of group VIIA and are highly reactive nonmetals. They have seven valence electrons and range from bein ggaseous to solids. Includes fluoride - chloride - and iodine

4. The energy required to completely remove an electron from an atom or an ion to make it ositive. the energy increases from left to right as the atomic radius diecreases

5. The degree that two liquids can mix together

6. Hydrocarbons that include carbon - carbon triple bonds

7. Occurs when one compound is replaced by an atom of another element like zinc metal

8. Small component of an atom that has no electrical charge

9. Anything that has mass and takes up space

10. Metals like calcium that produce alkaline solutions when combined with water. Part of Group IIA. Have two electrons in their outer shells

11. Chemicals like sodium that react with water to make alkaline solutions. Part of Group IA. They easily lose their valence electrons to become +1

12. Metals that conduct electricity

13. When elements from two different compounds didsplace each other to form new compounds - like when solutions of CaCl and HgNi combine to form insoluble HgCl and CaNi

14. When two reactants form one product - like sulfur dioxide by burning sulfur in the air

15. The smallest form of a particle

16. Metals that have low melting points

17. Negative charged ions

18. The way a periodic table is ordered in columns based on how many electrons are in the outer shell

19. The decay of a nuclei which results in the emission of certain particlces

20. Energy released when an electron is added to a gaseous atom

21. Small component of an atom that has a positive electrical charge

22. 1.66 x 10^-24 g

23. Hydrochloric acid

24. Ammonia

25. Metals mostly found in the middle of the table that are small and shiny. They are hard and have high melting and boiling points

26. An atom that has an electrical charge

27. Gases like neon and helium that do not interact with other elements because they havea complete valence shell

28. Metals that have a variety of property that include carbon - nitrogen and oxygen vital to the earth

29. The way of ordering the periodic table based on how many protons there are

30. The number of protons/electrons within an atom

31. When two different substances combine to form a new substance or when a substance breaks down to form two different substance.

32. The process of balancing chemical equations

33. Radioactive decay that leads to the emission of gamma particles

34. Hydrocarbons that have single bonds with a prefix to show the number of carbon atoms - like methane - ethane - propane - butane - pentane - and hexane

35. A chemical bond in which two atoms share electrons like H2.

36. The size of an atom that decreases across a period. Within the group - it increases from top to bottom

37. Hydrocarbons that involve carbon - carbon double bonds

38. The outer electron in a shell

39. The process in which a solid can become a gas - like dry ice

40. Positive charged ions

41. The conversion of liquid into a gas

42. Organic compounds that contain nitrogen - including protein

43. The transition from a gas into a solid

44. Substances that create hydroxide ions - have a pH level higher than 7 - and can conduct electricity

45. Radioactive decay in which a beta particle - aka an electron - is emitted

46. Radioactive decay in which half of a sample decays

47. The chemical potential for hydrogen - which determines whether or not a chemical is an acid or base

48. Carbons that consist of both hydrogen and carbon atoms and can be alkanes - alkenes - akynes - adn aromatics

49. The conversion of a gas back into a liquid

50. The bond formed when an anion and a cation unite and form a chemical reaction
