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






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






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






4. The degree that two liquids can mix together






5. 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






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






7. The conversion of liquid into a gas






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






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






10. Radioactive decay in which half of a sample decays






11. Organic compounds that contain nitrogen - including protein






12. The transition from a gas into a solid






13. 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






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. Positive charged ions






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

20. The process of balancing chemical equations






21. Sodium






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






23. Metals that have low melting points






24. 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






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






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






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






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






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






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






31. The outer electron in a shell






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






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






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






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






36. 1.66 x 10^-24 g






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






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






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






40. Ammonia






41. The number of protons/electrons within an atom






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






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






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






45. Hydrocarbons that involve carbon - carbon double bonds






46. Hydrocarbons that include carbon - carbon triple bonds






47. An atom that has an electrical charge






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






49. Metals that conduct electricity






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