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. Positive charged ions






2. Negative charged ions






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






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






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






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






7. Sodium






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






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






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






11. The conversion of liquid into a gas






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






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






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






15. Metals that have low melting points






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






17. Water






18. Organic compounds that contain nitrogen - including protein






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






20. Radioactive decay in which half of a sample decays






21. The transition from a gas into a solid






22. Metals that conduct electricity






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

25. The conversion of a gas back into a liquid






26. Hydrochloric acid






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






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






29. The degree that two liquids can mix together






30. 1.66 x 10^-24 g






31. Hydrocarbons that involve carbon - carbon double bonds






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






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






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






36. Components made up of a combination of atoms






37. 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






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






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






40. The number of protons/electrons within an atom






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






42. Ammonia






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






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






45. An atom that has an electrical charge






46. The smallest form of a particle






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






48. Hydrocarbons that include carbon - carbon triple bonds






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






50. The process of balancing chemical equations
