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






2. Metals that conduct electricity






3. 1.66 x 10^-24 g






4. Anything that has mass and takes up space






5. 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






6. The smallest form of a particle






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






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






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






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






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






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






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






14. Negative charged ions






15. Components made up of a combination of atoms






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






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






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






19. Hydrocarbons that involve carbon - carbon double bonds






20. Metals that have low melting points






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






22. The conversion of a gas back into a liquid






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






24. Sodium






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






26. The outer electron in a shell






27. An atom that has an electrical charge






28. Hydrocarbons that include carbon - carbon triple bonds






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






30. Water






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






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






33. The conversion of liquid into a gas






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






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






36. Organic compounds that contain nitrogen - including protein






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






38. 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






39. Move around the nucleus at the speed of light and have a negative charge






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






41. The process of balancing chemical equations






42. The transition from a gas into a solid






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






44. Ammonia






45. A chemical that is sour and stings and receives positive charged atoms when they are dissolved in water






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






47. Positive charged ions






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






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






50. The different forms of an electron based on their neutrons
