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. The number of protons/electrons within an atom






2. Anything that has mass and takes up space






3. The conversion of a gas back into a liquid






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






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






6. The degree that two liquids can mix together






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






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






9. The conversion of liquid into a gas






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






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






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






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






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






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






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






17. Ammonia






18. 1.66 x 10^-24 g






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






20. The transition from a gas into a solid






21. 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






22. 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






23. The smallest form of a particle






24. Metals that have low melting points






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






26. Sodium






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






28. Positive charged ions






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






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






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






32. Hydrocarbons that involve carbon - carbon double bonds






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






34. Components made up of a combination of atoms






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






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






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






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






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






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






41. The process of balancing chemical equations






42. Hydrocarbons that include carbon - carbon triple bonds






43. 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






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






45. Metals that conduct electricity






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






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






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






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






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