Subjects : cset, science, chemistry
Instructions:
  • 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. Hydrocarbons that involve carbon - carbon double bonds






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






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






4. Radioactive decay that leads to an emission of Helium -4 ion






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






6. Metals that conduct electricity






7. Distilled water - which has the ph level of 7






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






9. The smallest form of a particle






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






11. The conversion of a gas back into a liquid






12. 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






13. 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






14. Anything that has mass and takes up space






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






16. Hydrocarbons that include carbon - carbon triple bonds






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






18. Hydrocarbons taht also include oxygen - like alcohols - carbohydrates






19. 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






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






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






22. When a compound breaks down into two or more substances by heating - like the break down of mercury oxide






23. 1.66 x 10^-24 g






24. The center of an atom - which contains protons and neutrons






25. Water






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

28. Positive charged ions






29. Hydrochloric acid






30. Organic compounds that contain nitrogen - including protein






31. The outer electron in a shell






32. Sodium






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






34. Negative charged ions






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






36. 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






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






38. Radioactive decay in which half of a sample decays






39. Components made up of a combination of atoms






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






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






42. The transition from a gas into a solid






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






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






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






46. Metals that have low melting points






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






48. A specific type of double deplacement when an acid reactts with a base to form salt and water






49. Ammonia






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