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. Components made up of a combination of atoms






2. Positive charged ions






3. An atom that has an electrical charge






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






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






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






7. 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






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






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






10. The conversion of liquid into a gas






11. Metals that have low melting points






12. 1.66 x 10^-24 g






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






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






15. Hydrocarbons that involve carbon - carbon double bonds






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






17. The smallest form of a particle






18. Sodium






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






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






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






22. Organic compounds that contain nitrogen - including protein






23. The degree that two liquids can mix together






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






25. Radioactive decay in which half of a sample decays






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






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






28. The outer electron in a shell






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






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






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






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






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






34. The conversion of a gas back into a liquid






35. The transition from a gas into a solid






36. The process of balancing chemical equations






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






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






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






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






41. Metals that conduct electricity






42. Hydrochloric acid






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






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






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






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






47. Ammonia






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






49. Negative charged ions






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