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. The number of protons/electrons within an atom






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






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






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






6. An atom that has an electrical charge






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






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






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






10. Positive charged ions






11. 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






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






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






14. Sodium






15. 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






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






17. Hydrocarbons that include carbon - carbon triple bonds






18. Negative charged ions






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






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






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






22. The conversion of a gas back into a liquid






23. The process of balancing chemical equations






24. Ammonia






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






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






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






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






29. The conversion of liquid into a gas






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






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






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






33. The outer electron in a shell






34. 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






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






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






37. 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






38. Anything that has mass and takes up space






39. Radioactive decay in which half of a sample decays






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






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






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






43. 1.66 x 10^-24 g






44. Components made up of a combination of atoms






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






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






47. The smallest form of a particle






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






49. Metals that conduct electricity






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