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






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






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






4. An atom that has an electrical charge






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






6. Water






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






8. Hydrocarbons that involve carbon - carbon double bonds






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






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






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






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






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






14. Anything that has mass and takes up space






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






16. Hydrochloric acid






17. The transition from a gas into a solid






18. The conversion of a gas back into a liquid






19. The outer electron in a shell






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






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






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






23. Ammonia






24. Sodium






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






26. 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






27. Components made up of a combination of atoms






28. The number of protons/electrons within an atom






29. Metals that conduct electricity






30. 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






31. Radioactive decay in which half of a sample decays






32. 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






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






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






35. The smallest form of a particle






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






37. Positive charged ions






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






39. The degree that two liquids can mix together






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






41. Organic compounds that contain nitrogen - including protein






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






43. Negative charged ions






44. The process of balancing chemical equations






45. 1.66 x 10^-24 g






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






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






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






49. 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






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