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






3. Hydrocarbons that include carbon - carbon triple bonds






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






5. The transition from a gas into a solid






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






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






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






9. Radioactive decay in which half of a sample decays






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






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






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






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






14. The conversion of liquid into a gas






15. 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






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






17. Metals that have low melting points






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






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






20. 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






21. Water






22. The smallest form of a particle






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






24. The number of protons/electrons within an atom






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






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






27. Positive charged ions






28. Hydrocarbons that involve carbon - carbon double bonds






29. Hydrochloric acid






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






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






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. The conversion of a gas back into a liquid






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






35. The process of balancing chemical equations






36. Anything that has mass and takes up space






37. The degree that two liquids can mix together






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






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






40. 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






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






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






43. 1.66 x 10^-24 g






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






45. Sodium






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






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






48. Metals that conduct electricity






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






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