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






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






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






4. The conversion of a gas back into a liquid






5. Radioactive decay in which half of a sample decays






6. 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






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






8. The conversion of liquid into a gas






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






10. Negative charged ions






11. Components made up of a combination of atoms






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






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






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






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






16. Hydrochloric acid






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






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






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






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






21. The smallest form of a particle






22. Ammonia






23. Positive charged ions






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






25. The degree that two liquids can mix together






26. An atom that has an electrical charge






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






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






29. Organic compounds that contain nitrogen - including protein






30. The process of balancing chemical equations






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






32. Metals that conduct electricity






33. The transition from a gas into a solid






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






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






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






37. Metals that have low melting points






38. The outer electron in a shell






39. 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






40. Sodium






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






42. 1.66 x 10^-24 g






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






44. Anything that has mass and takes up space






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






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






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






48. Hydrocarbons that include carbon - carbon triple bonds






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






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