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






2. The number of protons/electrons within an atom






3. Positive charged ions






4. The process of balancing chemical equations






5. 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






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






7. Radioactive decay in which half of a sample decays






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






9. Anything that has mass and takes up space






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






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






12. Metals that conduct electricity






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






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






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






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






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






18. Organic compounds that contain nitrogen - including protein






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






20. The outer electron in a shell






21. Water






22. The smallest form of a particle






23. 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. Components made up of a combination of atoms






27. An atom that has an electrical charge






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






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






30. The degree that two liquids can mix together

32. Metals that have low melting points






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

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






41. The transition from a gas into a solid






42. The conversion of a gas back into a liquid






43. Hydrocarbons that involve carbon - carbon double bonds






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

46. 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






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






48. Small component of an atom that has a positive 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 chemical potential for hydrogen - which determines whether or not a chemical is an acid or base
