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






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






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






4. The conversion of a gas back into a liquid






5. Metals that conduct electricity






6. Water






7. Organic compounds that contain nitrogen - including protein






8. The conversion of liquid into a gas






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






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






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






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. The smallest form of a particle






14. 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






15. Hydrochloric acid






16. Components made up of a combination of atoms






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






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






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






20. Ammonia






21. Sodium






22. Hydrocarbons that involve carbon - carbon double bonds






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






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






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






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






27. Anything that has mass and takes up space






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






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






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






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






32. The process of balancing chemical equations






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






34. The outer electron in a shell






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






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






37. Metals that have low melting points






38. 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






39. An atom that has an electrical charge






40. The degree that two liquids can mix together






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






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






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






44. Negative charged ions






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






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






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






48. Radioactive decay in which half of a sample decays






49. 1.66 x 10^-24 g






50. 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
