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






2. 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






3. Ammonia






4. Water






5. The conversion of a gas back into a liquid






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






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






8. The number of protons/electrons within an atom






9. Sodium






10. An atom that has an electrical charge






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






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






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






14. The outer electron in a shell






15. Hydrocarbons that include carbon - carbon triple bonds






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






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






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






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






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






21. Metals that conduct electricity






22. The conversion of liquid into a gas






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






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






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






26. Positive charged ions






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






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






29. Metals that have low melting points






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






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






32. The process of balancing chemical equations






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






34. The transition from a gas into a solid






35. 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






36. Hydrocarbons that involve carbon - carbon double bonds






37. Radioactive decay in which half of a sample decays






38. Organic compounds that contain nitrogen - including protein






39. Negative charged ions






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






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






42. Hydrochloric acid






43. 1.66 x 10^-24 g






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






45. The degree that two liquids can mix together






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






47. 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






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






49. Anything that has mass and takes up space






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