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






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






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






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






5. Sodium






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






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






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






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






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






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






12. 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






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






14. Anything that has mass and takes up space






15. The transition from a gas into a solid






16. The process of balancing chemical equations






17. Positive charged ions






18. An atom that has an electrical charge






19. Metals that conduct electricity






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






21. Organic compounds that contain nitrogen - including protein






22. The degree that two liquids can mix together






23. The smallest form of a particle






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






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






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






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






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






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






30. 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






31. Negative charged ions






32. Ammonia






33. Components made up of a combination of atoms






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






35. The conversion of a gas back into a liquid






36. Hydrocarbons that include carbon - carbon triple bonds






37. The outer electron in a shell






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






39. Metals that have low melting points






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






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






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






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






44. The conversion of liquid into a gas






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






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






47. The number of protons/electrons within an atom






48. Hydrocarbons that involve carbon - carbon double bonds






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






50. 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
