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. Water






3. Hydrocarbons that involve carbon - carbon double bonds






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






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






6. 1.66 x 10^-24 g






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






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






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






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






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






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






13. The conversion of liquid into a gas






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






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






16. The degree that two liquids can mix together






17. The conversion of a gas back into a liquid






18. Organic compounds that contain nitrogen - including protein






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






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






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






22. The smallest form of a particle






23. 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






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






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






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






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






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






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






30. Positive charged ions






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






32. Hydrochloric acid






33. Radioactive decay in which half of a sample decays






34. The outer electron in a shell






35. Components made up of a combination of atoms






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






37. 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






38. Anything that has mass and takes up space






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






40. Ammonia






41. The process of balancing chemical equations






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






43. Negative charged ions






44. An atom that has an electrical charge






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






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






47. 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






48. Metals that have low melting points






49. 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






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