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. Ammonia






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






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






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






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






6. Positive charged ions






7. An atom that has an electrical charge






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






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






10. Hydrocarbons that involve carbon - carbon double bonds






11. The smallest form of a particle






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






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






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






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






16. 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






17. Sodium






18. The number of protons/electrons within an atom






19. Metals that conduct electricity






20. Anything that has mass and takes up space






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






22. The conversion of liquid into a gas






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






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






25. Hydrocarbons that include carbon - carbon triple bonds






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






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






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






29. The conversion of a gas back into a liquid






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






31. Water






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






33. The outer electron in a shell






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






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






36. 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






37. The transition from a gas into a solid






38. 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






39. Hydrochloric acid






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






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






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






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






44. Metals that have low melting points






45. The degree that two liquids can mix together






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






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






48. 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






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






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