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 number of protons/electrons within an atom






2. The smallest form of a particle






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






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






5. Hydrochloric acid






6. 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






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






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






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






10. 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






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






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






13. Hydrocarbons that involve carbon - carbon double bonds






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






15. Radioactive decay in which half of a sample decays






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






17. The process of balancing chemical equations






18. The transition from a gas into a solid






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






20. Sodium






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






22. Metals that have low melting points






23. Metals that conduct electricity






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






25. 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






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






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






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






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






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






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






32. Hydrocarbons that include carbon - carbon triple bonds






33. An atom that has an electrical charge






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. 1.66 x 10^-24 g






36. Ammonia






37. Negative charged ions






38. The outer electron in a shell






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






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






41. The conversion of a gas back into a liquid






42. Positive charged ions






43. The conversion of liquid into a gas






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






45. The degree that two liquids can mix together






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






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






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






49. Water






50. Components made up of a combination of atoms
