CSET Science: Chemistry

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






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






3. The outer electron in a shell






4. An atom that has an electrical charge






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






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






7. Positive charged ions






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. Hydrocarbons that involve carbon - carbon double bonds






10. The number of protons/electrons within an atom






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






12. Ammonia






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






14. Hydrocarbons that include carbon - carbon triple bonds






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






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






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






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






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






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






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






22. The smallest form of a particle






23. Hydrochloric acid






24. Negative charged ions






25. Organic compounds that contain nitrogen - including protein






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






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






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






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






30. Metals that have low melting points






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






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






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






35. Radioactive decay in which half of a sample decays






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






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






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






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






40. 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






41. The conversion of liquid into a gas






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






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






44. The conversion of a gas back into a liquid






45. Anything that has mass and takes up space






46. The process of balancing chemical equations






47. 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






48. 1.66 x 10^-24 g






49. Metals that conduct electricity






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