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 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






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






3. 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






4. 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






5. The degree that two liquids can mix together






6. Hydrocarbons that include carbon - carbon triple bonds






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






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






9. Anything that has mass and takes up space






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






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






12. Metals that conduct electricity






13. 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






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






15. The smallest form of a particle






16. Metals that have low melting points






17. Negative charged ions






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






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






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






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






22. 1.66 x 10^-24 g






23. Hydrochloric acid






24. Ammonia






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






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






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






30. The number of protons/electrons within an atom






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






32. The process of balancing chemical equations






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






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






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






37. Hydrocarbons that involve carbon - carbon double bonds






38. The outer electron in a shell






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






40. Positive charged ions






41. The conversion of liquid into a gas






42. Organic compounds that contain nitrogen - including protein






43. The transition from a gas into a solid






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






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






46. Radioactive decay in which half of a sample decays






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






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






49. The conversion of a gas back into a liquid






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