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. The conversion of liquid into a gas






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






3. The transition from a gas into a solid






4. 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






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






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






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






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






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






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






11. Occurs when one compound is replaced by an atom of another element like zinc metal






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






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






14. Sodium






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






16. The degree that two liquids can mix together






17. The smallest form of a particle

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






20. Hydrochloric acid






21. Organic compounds that contain nitrogen - including protein






22. Positive charged ions






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






24. Negative charged ions






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






26. The conversion of a gas back into a liquid






27. Hydrocarbons that involve carbon - carbon double bonds






28. 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






29. Radioactive decay in which half of a sample decays






30. The outer electron in a shell






31. Components made up of a combination of atoms






32. The process of balancing chemical equations






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






34. Ammonia






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






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






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






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






39. Water






40. The number of protons/electrons within an atom






41. An atom that has an electrical charge






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






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






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






45. Metals that conduct electricity






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






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






48. Hydrocarbons that include carbon - carbon triple bonds






49. 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






50. 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
