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






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






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






4. The conversion of liquid into a gas






5. The outer electron in a shell






6. The conversion of a gas back into a liquid






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






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






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






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






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






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






13. Hydrocarbons that include carbon - carbon triple bonds






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






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






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






17. The smallest form of a particle






18. Organic compounds that contain nitrogen - including protein






19. 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






20. Water






21. 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






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






23. Components made up of a combination of atoms






24. Metals that conduct electricity






25. Negative charged ions






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






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






28. The number of protons/electrons within an atom






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






30. Hydrochloric acid






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






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






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

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






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






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






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






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






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






46. Positive charged ions
