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. Metals that conduct electricity






3. Anything that has mass and takes up space






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






5. An atom that has an electrical charge






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






7. Negative charged ions






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






9. Hydrocarbons that involve carbon - carbon double bonds






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. Hydrochloric acid






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






14. 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






15. The outer electron in a shell






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






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






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






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






20. Organic compounds that contain nitrogen - including protein






21. Hydrocarbons that include carbon - carbon triple bonds






22. The process of balancing chemical equations






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






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






25. Radioactive decay in which half of a sample decays






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






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






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






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






30. The number of protons/electrons within an atom






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






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






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






34. 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

45. Components made up of a combination of atoms






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






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






48. 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






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






50. The degree that two liquids can mix together
