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 that have low melting points






2. Negative charged ions






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






5. Hydrochloric acid






6. 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






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






8. The conversion of a gas back into a liquid






9. Components made up of a combination of atoms






10. 1.66 x 10^-24 g






11. 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






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






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






14. The degree that two liquids can mix together






15. 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






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






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






18. Water






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






20. Hydrocarbons that include carbon - carbon triple bonds






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






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






23. Sodium






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






25. Metals that conduct electricity






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






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






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






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






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






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






32. Organic compounds that contain nitrogen - including protein






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






34. The outer electron in a shell






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






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






37. Radioactive decay in which half of a sample decays






38. An atom that has an electrical charge






39. Ammonia






40. The transition from a gas into a solid






41. Hydrocarbons that involve carbon - carbon double bonds






42. Positive charged ions






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






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






45. Anything that has mass and takes up space






46. Distilled water - which has the ph level of 7






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






48. The number of protons/electrons within an atom






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






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